  • What is a circulation system in drilling?
    What is a circulation system in drilling?
    Apr 11, 2025
    The drilling rig circulation system is an extremely important part of oil drilling and other operations. It is mainly responsible for the circulation of drilling fluid to achieve functions such as carrying cuttings, cooling the drill bit, lubricating the drilling tools, and balancing the formation pressure. The following is a detailed introduction: Ⅰ. Main Components 1.Drilling Pump Function: It is the core equipment of the circulation system, used to provide power for the circulation of the drilling fluid. It pumps the drilling fluid from the mud pit into the drill string and then sprays it out through the drill bit nozzles. Common drilling pumps include piston pumps, and the F type drilling mud pump is widely used, which has the characteristics of large displacement and high pressure. Type: In common piston pumps, the piston moves back and forth in the cylinder to suck in and discharge the drilling fluid. When the piston moves backward, the volume inside the cylinder increases, the pressure decreases, and the drilling fluid enters the cylinder through the suction valve under the action of atmospheric pressure. When the piston moves forward, the drilling fluid in the cylinder is squeezed, the pressure rises, and the discharge valve is opened to discharge the drilling fluid from the cylinder, thus realizing the suction and discharge process of the drilling fluid. It has the characteristics of large displacement and high pressure and is suitable for various drilling operations. 2.Mud Pit and Storage Tank Function: The mud pit is used to store the drilling fluid and also plays a role in the preliminary precipitation of cuttings during the circulation of the drilling fluid.The storage tank is used to store a large amount of drilling fluid to meet the circulation requirements during the drilling process. The volume of the mud tank is determined according to the scale and requirements of the drilling operation. Usually, multiple mud tanks are connected to form a complete storage system. 3.Mud Purification Equipment It includes drilling fluid shale shakers, desanders, desilters, mud centrifugal pumps, etc. The shale shaker is mainly used to remove larger particles of cuttings in the drilling fluid. The desander and desilter are respectively used to remove smaller particles of sand and mud. The centrifugal mud pump can further separate finer solid particles and weighting materials, purify the drilling fluid, and make it reusable. 4.Drill String and Drill Bit The drill string is the passage for the drilling fluid. The drilling fluid flows downward through the inside of the drill string, and after being sprayed out from the nozzles of the drill bit, it carries the cuttings and returns to the surface along the annulus between the wellbore and the drill string. The design of the drill bit nozzles has an important influence on the spraying speed and flow pattern of the drilling fluid, thus affecting the carrying capacity of the cuttings. The components of the drill string include drill pipes and drill collars. Drill Pipe: It is the main component of the drill string, used to connect the swivel and the drill bit to form a passage for the drilling fluid. Drill pipes are usually made of high-strength alloy steel, which has high strength and toughness and can withstand various loads such as tension, compression, and torsion during the drilling process. Special threads are processed at both ends of the drill pipe for connecting adjacent drill pipes and other drilling tools. Drill Collar: It is generally located at the lower part of the drill string, close to the drill bit. The main function of the drill collar is to provide sufficient weight on bit (WOB) for the drill bit so that the drill bit can effectively break the rock. The drill collar is usually shorter and thicker than the drill pipe, with a large weight and stiffness, which can maintain a stable posture during the drilling process and prevent excessive bending and swinging of the drill string. 5.Surface Manifolds It connects various components such as the drilling pump, drill string, mud purification equipment, and mud pit, forming a passage for the circulation of the drilling fluid. The surface manifolds need to have good sealing performance and pressure resistance to ensure the smooth circulation of the drilling fluid. Suction Manifold: It connects the mud tank and the inlet of the drilling pump and is used to smoothly transport the drilling fluid in the mud tank to the drilling pump. The suction manifold usually includes suction pipelines, suction valves, filters, and other components. The filter can prevent large-particle impurities from entering the drilling pump and avoid damage to the pump. Discharge Manifold: It transports the high-pressure drilling fluid discharged from the drilling pump to the standpipe and subsequent equipment. Various valves such as safety valves, throttle valves, and mud gate valves are installed on the discharge manifold to control the flow rate, pressure, and flow direction of the drilling fluid. The safety valve can automatically open to release the pressure when the system pressure is too high to protect the equipment safety. The throttle valve is used to precisely adjust the flow rate of the drilling fluid to meet the needs of different drilling conditions. 6.Standpipe and Hose Standpipe: It is a vertical pipe installed beside the derrick, which transports the high-pressure drilling fluid in the surface manifolds to the upper part of the wellhead. The standpipe is usually made of high-strength steel pipes and can withstand the pressure of high-pressure drilling fluid. For the convenience of installation and maintenance, the standpipe is generally composed of multiple sections, and the sections are connected by flanges or threads. Hose: It is a flexible high-pressure hose connecting the standpipe and the swivel. The hose has good flexibility and pressure resistance and can swing flexibly with the up-and-down movement and rotation of the drilling tools to ensure that the drilling fluid can be smoothly transported from the standpipe to the drill string. The inside of the hose is usually made of wear-resistant and corrosion-resistant materials to extend its service life. 7.Swivel Rotation Function: It allows the drill string to move up and down while rotating, enabling the drilling fluid to enter the inside of the drill string through the swivel. The rotating part of the drilling rotary swivel uses high-precision bearings and sealing devices, which can maintain good sealing performance and stability in a high-speed rotation and high-pressure environment. Loading Function: It bears the weight of the drill string and various axial and radial forces generated during the drilling process. The outer shell and internal structure of the swivel have sufficient strength and stiffness to ensure safe and reliable operation throughout the drilling process. Ⅱ. Overall Working Principle The drilling pump sucks the treated drilling fluid from the mud tank and enters the pump body through the suction manifold. Under the action of the pump, the drilling fluid is pressurized to the required pressure and then transported to the standpipe through the discharge manifold. The standpipe transports the high-pressure drilling fluid vertically upward to the hose at the top of the derrick. The hose introduces the drilling fluid into the swivel, and the swivel distributes the drilling fluid into the inside of the drill string. The drilling fluid flows downward along the axis inside the drill string. After reaching the drill bit, it is sprayed out at a high speed from the nozzles of the drill bit. The design of the nozzles enables the drilling fluid to impact the rock at the bottom of the well at a high speed to assist the drill bit in breaking the rock. At the same time, after being sprayed out from the drill bit, the drilling fluid carries the cuttings at the bottom of the well and enters the annulus between the drill string and the wellbore together. In the annulus, the drilling fluid carries the cuttings and flows upward to return to the surface. The drilling fluid returning to the surface enters the mud tank through the surface manifolds. In the mud tank, the drilling fluid is first agitated by the agitator to keep the solid particles in suspension. Then, it passes through treatment equipment such as the desander, desilter, and centrifuge in turn to remove the cuttings, sand particles, and other harmful components. The treated drilling fluid is sucked in by the drilling pump again to start a new cycle. Ⅲ. Function and Importance Carrying Cuttings: It timely carries the cuttings broken by the drill bit from the bottom of the well to the surface, preventing the cuttings from accumulating at the bottom of the well and affecting the drilling efficiency and the service life of the drill bit. Cooling and Lubricating: During the circulation process, the drilling fluid can take away the heat generated by the drill bit and the drill string during the drilling process, playing a cooling role. At the same time, it can also form a lubricating film between the drill string and the wellbore, reducing the frictional resistance and reducing the wear of the drilling tools. Balancing Formation Pressure: The drilling fluid with appropriate performance can balance the formation pressure, prevent formation fluids (such as oil, gas, and water) from flowing into the wellbore, avoid accidents such as blowouts, and ensure the safety of the drilling operation. Protecting the Wellbore Wall: The mud cake formed by the drilling fluid on the wellbore wall can play a role in stabilizing the wellbore wall, preventing the wellbore wall from collapsing, and maintaining the integrity of the wellbore. Ⅳ. Maintenance Points Maintenance of the Drilling Pump: Regularly check the wear conditions of vulnerable parts such as the piston, cylinder liner, and valve seat of the pump, and replace the severely worn parts in a timely manner. Keep the lubrication system and cooling system of the pump working normally. Regularly check the oil level and quality of the lubricating oil to ensure that the cooling water is sufficient. In addition, it is also necessary to regularly clean the pump to prevent impurities such as mud from accumulating on the surface and inside of the pump body. Maintenance of the Manifolds: Check whether there are leakage phenomena at the connection parts of the manifolds, and tighten the loose bolts or replace the seals in a timely manner. Regularly clean the dirt and debris inside the manifolds to prevent them from blocking the pipelines. Maintain the valves on the manifolds to ensure that the valves can be opened and closed flexibly and have good sealing performance. Regularly lubricate and maintain the valves to prevent the valves from rusting and jamming. Maintenance of the Standpipe and Hose: Check whether the fixing of the standpipe is firm and whether there are deformation or corrosion phenomena. Regularly check the welds of the standpipe to prevent the occurrence of defects such as cracks. Avoid excessive bending and stretching of the hose. Regularly check whether there are damages such as cracks and bulges on the surface of the hose. If there is any damage, it should be replaced in a timely manner. At the same time, keep the hose clean and avoid impurities such as mud adhering to the surface, which will affect its performance. Maintenance of the Swivel: Regularly check the rotating part and the sealing part of the swivel to ensure that it rotates flexibly and has good sealing performance. Lubricate and maintain the bearings of the swivel and replace the lubricating grease regularly. Check whether there are cracks or deformations in components such as the bail and gooseneck of the swivel. If there are any problems, they should be repaired or replaced in a timely manner. Maintenance of the Drill String: During the tripping operation, pay attention to the operation specifications to avoid excessive impact and bending of the drill string. Regularly check whether the threads of the drill pipe and drill collar are worn, deformed, or damaged, and clean, grease, and repair the threads in a timely manner. Conduct non-destructive testing on the drill string to check whether there are defects such as cracks inside to ensure the safety and reliability of the drill string. Maintenance of the Mud Tank: Regularly clean the sand and debris in the mud tank to keep the tank clean. Check whether the blades of the agitator are worn, and replace the damaged blades in a timely manner to ensure the normal operation of the agitator. Carry out anti-corrosion treatment on the tank body of the mud tank to prevent the tank body from being corroded by the drilling fluid. At the same time, regularly check whether the instruments such as the level gauge and thermometer of the mud tank are working normally to ensure that the parameters of the drilling fluid can be accurately measured and monitored.

  • From Principle to Advantages: A Comprehensive Interpretation of Demco Mud Gate Valve
    From Principle to Advantages: A Comprehensive Interpretation of Demco Mud Gate Valve
    Feb 11, 2025
    Demco Type Mud Gate Valve are top-notch designed gate valves in the oil and gas drilling market, specifically manufactured to meet the stringent requirements of oilfield applications. They are suitable for heavy-duty performance under harsh service conditions and are commonly found in various oilfield applications such as drilling riser manifolds, pump manifold stop valves, high-pressure mud lines, high-pressure and fracturing services, production manifolds, production gathering systems, and production flow lines. I. Structural Design The mud gate valve mainly consists of a valve body, valve cover, valve seat, gate plate, valve stem, valve stem nut, handle, O-ring, etc. The design, manufacturing, flange connection form, inspection, and testing of the valve comply with the provisions of API Spec 6A standard, and the threaded connection form complies with the provisions of API 5B standard. Valve Type: Usually designed as a parallel-slide gate valve, the gate plate is flat-shaped and moves perpendicular to the fluid flow path to control the fluid flow rate. This design allows the fluid to pass through unobstructed when the valve is open, reducing flow resistance and contributing to improving drilling efficiency. Materials: It is made of high-quality materials such as carbon steel and stainless steel, which can withstand harsh conditions such as high temperature, high pressure, and mud scouring during drilling operations, ensuring the strength and durability of the valve and extending its service life. Connection Methods: It provides various end-connection methods, such as threaded connection, welding, ferrule connection, and flange connection, etc. These can be selected according to different installation locations and pipeline system requirements, facilitating connection to the pipeline system of drilling equipment. II. Working Principle Manual Operation: By rotating the handwheel, the valve stem is driven to move linearly. The valve stem is connected to the gate plate, causing the gate plate to move up and down in the valve body. When the gate plate rises, the valve opens, and fluids such as mud can pass through the valve passage; when the gate plate descends, the gate plate fits tightly against the valve seat, blocking the fluid flow, thus achieving control over the flow rate and direction of the mud. Remote Control: It can be equipped with a hydraulic or pneumatic actuator. The control system sends signals remotely to control the action of the actuator, which in turn drives the movement of the valve stem and the gate plate, enabling remote opening and closing of the valve to meet the demand for precise valve control in complex drilling environments. III. Performance Characteristics Full-Bore Design: The inner diameter of the valve passage is the same as that of the pipeline, allowing fluids such as mud to flow smoothly in the pipeline, reducing the pressure loss of the fluid at the valve, improving the circulation efficiency of the drilling fluid, and contributing to optimizing the drilling operation process. Bi-Directional Sealing: It has a bi-directional sealing function, meaning that regardless of the direction of fluid flow, a good seal can be formed between the gate plate and the valve seat to prevent fluid leakage, ensuring well control safety during the drilling process and increasing the valve's applicability under different working conditions. Maintainability: The valve cover is easy to disassemble. Internal parts can be inspected or replaced without removing the valve from the pipeline. This design is simple, quick, and easy to maintain without the need for special tools. Diverse Pressure Ratings: It has a wide range of pressure ratings, such as 2000psi, 3000psi, 5000psi, 7500psi, etc., which can meet the mud transportation requirements in different pressure environments, being applicable to both shallow well and deep-well drilling. High Wear Resistance: Since mud often contains solid particles that can cause wear to the valve, components of the Demco mud gate valve that come into contact with the mud, such as the gate plate and valve seat, are usually made of wear-resistant materials such as cemented carbide and high-strength alloy steel. Through special surface treatment processes such as spraying and surfacing, the surface hardness and wear resistance are enhanced, extending the valve's service life and reducing maintenance and replacement costs. IV. Application Fields Oil and Gas Drilling: In drilling operations, it is used to control the flow of drilling mud, achieving operations such as mud circulation, discharge, and throttling, ensuring the pressure balance and stability of the wellbore during the drilling process, and preventing accidents such as blowouts. Completion and Workover Operations: During well completion and workover processes, it is used to control the flow of fluids such as cement slurry and fracturing fluid, ensuring the smooth progress of the operations and effectively plugging and isolating the wellbore. Petrochemical Pipeline Systems: In the pipeline systems of petrochemical production, it is used to control the flow of various fluids containing solid particles or corrosive media, such as crude oil transportation and slurry transportation during petroleum refining. V. Functions of Accessories Cut-off Function: It can quickly cut off the flow of mud in the pipeline. For example, during drilling operations, when it is necessary to repair, replace components, or handle faults in a certain section of the pipeline, the valve can be quickly closed to stop the mud from flowing, facilitating safe operations. Flow Regulation: By changing the opening degree of the valve, the flow rate of the mud can be precisely controlled to meet the requirements of different working conditions. For example, in oil extraction, according to the drilling depth, formation conditions, and drill bit wear, the mud flow rate can be reasonably adjusted to ensure drilling efficiency and quality. Backflow Prevention: It can effectively prevent the backflow of mud in the pipeline, avoiding damage to equipment and pipelines caused by mud backflow or affecting the normal operation of the entire process flow, ensuring the stability and safety of the pipeline system. Reducing Pressure Loss: With a reasonable structural design, it can reduce the pressure loss of the mud in the valve, improve energy utilization efficiency, and reduce additional energy consumption and equipment load caused by excessive pressure loss. VI. Storage and Installation Storage: If the valve needs to be stored for a long time, it should be stored in a dry and ventilated indoor environment, avoiding direct sunlight and a humid environment. The inlet and outlet of the valve should be sealed with plastic sheets or other sealing materials to prevent dust and debris from entering. Regularly inspect and maintain the stored valve, and apply anti-rust oil to prevent rusting. Installation: During installation, ensure that the valve is installed in the correct direction, is firmly connected to the pipeline, and has a good seal. Avoid collisions and damage to the valve during the installation process. After installation, conduct a pressure test and a sealing test to check whether the valve performance meets the requirements. VII. Operation Precautions Manual Operation: When operating the handwheel, apply force evenly. Do not use a force-increasing rod or excessive force to avoid damaging the valve stem, valve stem nut, or gate plate. Operate according to the marked opening and closing direction to avoid reverse operation. Electric or Pneumatic Operation: Regularly check the control system, air source, or power supply of the electric or pneumatic device to ensure its normal operation. During the operation process, if any abnormal conditions are found, such as motor overload or cylinder air leakage, stop the operation immediately and conduct inspections and repairs. Medium Requirements: Avoid mixing overly large particles or impurities into the mud to prevent wear and blockage of the valve's sealing surface and internal components. For mud containing corrosive media, select a valve with a suitable material according to the nature of the media and take corresponding anti-corrosion measures. VIII. Fault Troubleshooting 1.Sealing Leakage Problems with the Sealing Surface between the Gate Plate and the Valve Seat       Inspection Content: Check whether the sealing surface has wear, scratches, corrosion, or deformation. After long-term use, the scouring and wear of the mud may cause the sealing surface to become uneven, affecting the sealing effect.       Troubleshooting Method: Disassemble the valve, visually inspect the condition of the sealing surface, or use special detection tools such as a sealing surface flatness detection ruler. If the sealing surface is damaged, it is usually necessary to grind or replace the gate plate and the valve seat. Aging or Damage of the Sealing Ring       Inspection Content: Check whether the sealing ring has aging, cracking, deformation, or damage. The sealing ring is prone to aging and damage when it is in a high-pressure, high-temperature, or corrosive medium for a long time.       Troubleshooting Method: Observe the appearance of the sealing ring and check its elasticity and integrity. If there are problems, replace the sealing ring in a timely manner to ensure that its material and specifications are the same as the original one. Leakage at the Connection between the Valve Body and the Valve Cover        Inspection Content: Check whether the connecting bolts are loose and whether the sealing gasket is damaged. Loose bolts will increase the gap at the connection, and a damaged gasket will directly affect the sealing performance.       Troubleshooting Method: Use a torque wrench to check the bolt torque. If loose, tighten them according to the specified torque; disassemble and check the sealing gasket. If damaged, replace it with a new one. 2.Difficult Valve Operation Sticking of the Valve Stem       Inspection Content: Check whether the valve stem surface has wear, corrosion, scratches, or impurities attached. The valve stem is in contact with the mud for a long time, and these problems are likely to occur, increasing the friction between the valve stem and the stuffing box.       Troubleshooting Method: Disassemble the valve stem, clean the surface impurities, and observe the wear situation. Slight wear can be polished and repaired, and severe wear requires replacement of the valve stem. At the same time, check whether the stuffing box is deformed or damaged and deal with it in a timely manner if there are problems. Faults in the Transmission Components        Inspection Content: For manual valves, check whether the handwheel, valve stem nut, and other transmission components are worn, damaged, or jammed; for electric or pneumatic valves, check whether the motor, cylinder, gears, and other transmission components are working properly.        Troubleshooting Method: During manual operation, feel the resistance of the handwheel rotation and observe the movement of the transmission components; for electric or pneumatic valves, check whether the motor is powered on, whether the cylinder is supplied with air, and whether there are obvious signs of damage to each transmission component. If there are faults, repair or replace the damaged transmission components. Jamming of the Gate Plate        Inspection Content: Check whether the gate plate is stuck due to impurities, agglomerates, or foreign objects in the mud, and whether there is excessive friction between the gate plate and the valve seat.        Troubleshooting Method: Disassemble the valve, clean the impurities and foreign objects around the gate plate and the valve seat, and check the fit clearance between the gate plate and the valve seat. If necessary, repair or adjust the gate plate and the valve seat. 3.Internal Leakage of the Valve Damage to the Sealing Surface        Inspection Content: Similar to the method of checking the sealing surface for sealing leakage, focus on checking whether the sealing surface has small cracks, wear, or corrosion pits. These defects may cause the valve to be unable to seal completely when closed, resulting in internal leakage.        Troubleshooting Method: Conduct a sealing test using high-pressure water or gas, and observe whether there is any leakage inside the valve. If there is internal leakage, disassemble the valve to check the sealing surface and repair or replace it according to the degree of damage. Deformation of the Gate Plate        Inspection Content: Check whether the gate plate is deformed due to long-term stress or uneven medium pressure. The deformed gate plate may not fit tightly against the valve seat, resulting in internal leakage.        Troubleshooting Method: Disassemble the gate plate, use professional measuring tools to check the flatness and dimensions of the gate plate. If deformation is found, correct or replace the gate plate according to the specific situation. 4.External Leakage of the Valve Leakage of the Stuffing Box        Inspection Content: Check whether the packing is aging, worn, or improperly installed. The stuffing box is a key component to prevent leakage at the valve stem, and the performance and installation quality of the packing directly affect the sealing effect.        Troubleshooting Method: Observe whether there is mud seepage at the stuffing box. Disassemble the stuffing box and check the condition of the packing. If the packing is aging or worn, replace it with new packing and ensure that the packing is installed tightly and evenly. Sand Holes or Cracks in the Valve Body        Inspection Content: Check whether there are sand holes, cracks, or other defects on the surface of the valve body. These defects may be caused by casting quality problems or long-term exposure to pressure, corrosion, and other factors.        Troubleshooting Method: Use methods such as visual inspection, penetrant testing, or ultrasonic testing to find sand holes or cracks on the valve body. For small sand holes, methods such as repair welding can be used; for cracks, the valve body generally needs to be replaced.
