Description

Technical Field

[0001] This utility model relates to the field of oil and gas drilling and production equipment, specifically to a remote connection and disconnection control system for oil pipes used in pressurized operations and pressurized operation equipment. Background Technology

[0002] During pressurized well workover operations in oil and gas fields, the iron roughneck, as a key piece of equipment, is indispensable, but its traditional operation has significant drawbacks. Primarily used for connecting and disconnecting tubing joints and performing threading tasks, the traditional iron roughneck requires workers to be physically present on the high-pressure work platform for manual control. This method not only directly exposes workers to high-pressure risks but also forces them to physically operate heavy machinery to complete complex tasks, greatly increasing workload and safety hazards.

[0003] Especially in oil and gas fields located in areas with extremely harsh natural conditions—where strong winds, extreme cold, and other extreme weather events are frequent—the traditional operating methods of iron drill operators further amplify safety risks. The harsh working environment combined with the need for manual operation not only increases the accident rate but also poses a serious threat to workers' health. Therefore, the traditional operating methods of iron drill operators demonstrate significant shortcomings in both safety and work efficiency, and urgently need improvement to meet the safety standards and efficiency requirements of modern oil and gas field operations.

[0028] Example 1

[0029] This embodiment describes a remote connection / disconnection control system for oil pipes used in pressurized operations. See also... Figure 1 The remote pipe coupling / uncoupling control system for pressurized operations provided in this embodiment includes: a control unit 100, a monitoring unit 200, a hydraulic adjustment unit 300, and a hydraulic drill 400. The monitoring unit 200 and the hydraulic adjustment unit 300 are electrically connected to the control unit 100. The power unit of the hydraulic drill 400 is connected to the hydraulic adjustment unit 300 via a hydraulic line. The hydraulic drill 400 is used to perform pipe coupling / uncoupling operations. The monitoring unit 200 is used to monitor the operating status of the hydraulic drill 400 in real time. The control unit 100 can generate control commands based on the monitoring data from the monitoring unit 200 and send them to the hydraulic adjustment unit 300. The hydraulic adjustment unit 300 adjusts the hydraulic oil delivery according to the control commands, thereby adjusting the operating status of the hydraulic drill 400 to complete the pipe coupling / uncoupling operations.

[0030] This embodiment utilizes a monitoring unit 200 to monitor the real-time operating status of the drill 400 and sends control commands to the hydraulic adjustment unit 300 via the control unit 100.

During the coupling and uncoupling operation using this invention, the monitoring unit 200 monitors the real-time operating status of the drill 400, and the worker can adjust each power component of the drill 400 through the control unit 100 to ensure the accuracy of the coupling and uncoupling operation.

[0031] Example 2

[0032] This embodiment is a further improvement upon embodiment 1; repeated content will not be elaborated further. See also... Figure 2 Preferably, the iron drill 400 includes: a main clamp 410 for clamping the upper pipe; a rotating mechanism 420 for rotating the main clamp 410; and a spare clamp 430 for clamping the lower pipe. The main clamp 410 is positioned above the rotating mechanism 420, and the spare clamp 430 is positioned below the rotating mechanism 420. The spare clamp 430 is closer to the wellbore, and the main clamp 410 is farther from the wellbore. The rotating mechanism 420 is positioned between the main clamp 410 and the spare clamp 430. The upper pipe refers to the pipe that is farther from the wellbore during the upper / lower connection operation; the lower pipe refers to the pipe that is closer to the wellbore or located within the wellbore during the upper / lower connection operation.

[0033] Preferably, the power components of the iron drill 400 include: a main clamp cylinder 411 configured in the main clamp 410, a hydraulic motor 421 configured in the rotary mechanism 420, and a backup clamp cylinder 431 configured in the backup clamp 430. The main clamp cylinder 411, the hydraulic motor 421, and the backup clamp cylinder 431 are respectively connected to the hydraulic regulating unit 300 via hydraulic lines. The hydraulic regulating unit 300 can control the working parameters of the main clamp 410, the hydraulic motor 421, and the backup clamp cylinder 431 by adjusting the hydraulic parameters of the main clamp cylinder 411, the hydraulic motor 421, and the backup clamp cylinder 431. Preferably, the rotary mechanism 420 is a hydraulic rotary mechanism (also known as a hydraulic rotary transmission device), which may include a hydraulic motor 421, a brake, a reducer, a valve group, and a gear end structure. This hydraulic rotary mechanism can adjust the torque, speed, etc. of the hydraulic rotary mechanism by adjusting the hydraulic parameters (such as pressure, flow rate, flow direction, etc.) of the hydraulic motor 421. Preferably, the rotary mechanism 420 is a hydraulic rotary mechanism, which can provide more powerful torque, enabling the Iron Drill 400 to easily handle high-strength, large-size pipe column connections.

[0034] See Figure 1 and Figure 2 Preferably, the monitoring unit 200 includes: a camera 210 for acquiring images of the docking of the upper and lower pipes; and an encoder 220, configured on the rotary mechanism 420, for acquiring the number of rotations and rotational speed of the rotary mechanism 420. The camera 210 and the encoder 220 are electrically connected to the control unit 100.

[0035] Preferably, the hydraulic parameters include: hydraulic pressure, flow rate, and flow direction. The hydraulic adjustment unit 300 can adjust the hydraulic parameters of the main clamp cylinder 411 to clamp or release the main clamp 410. The hydraulic adjustment unit 300 can adjust the hydraulic parameters of the hydraulic motor 421 to control the speed and direction of rotation of the hydraulic motor 421, thereby controlling the speed and direction of rotation of the main clamp 410 driven by the rotary mechanism 420. The hydraulic adjustment unit 300 can adjust the hydraulic parameters of the spare clamp cylinder 431 to clamp or release the spare clamp 430. Preferably, after the clamping is completed or after the unclamping is completed, the control unit 100 controls the main clamp 410 and the spare clamp 430 to release through the hydraulic adjustment unit 300.

[0036] See Figure 2 Preferably, the main clamp 410 is equipped with a first mounting housing 412, which is elastically connected to the rotary mechanism 420 via four elastic components. The backup clamp 430 is equipped with a second mounting housing, which is fixedly connected to the rotary mechanism 420. Preferably, the first mounting housing 412 has a cuboid structure with six openings on each side; the first mounting housing 412 has a through hole 413 for the oil supply pipe to pass through. An overflow cavity is provided inside the second mounting housing. Preferably, the main clamp 410 is equipped with two main clamp jaws. The two main clamp jaws are respectively installed on the left and right sides of the first mounting housing 412. The two main clamp jaws are arranged opposite each other. Each of the two main clamp jaws is equipped with a main clamp hydraulic cylinder 411. The output end of the main clamp hydraulic cylinder 411 is connected to the main clamp jaw. The backup clamp 430 is equipped with two backup clamp jaws. The two backup clamp jaws are respectively installed on the left and right sides of the second mounting housing. The two backup clamp jaws are arranged opposite each other. Each of the two backup clamp jaws is equipped with a backup clamp hydraulic cylinder 431. The output end of the spare clamp cylinder 431 is connected to the spare clamp jaws.

[0037] When the upper pipe is positioned between the two main clamp teeth, the output end of the main clamp cylinder 411 pushes the main clamp teeth, bringing the two opposing main clamp teeth closer together and clamping the tubing string. The main clamp teeth are generally arc-shaped, allowing them to conform to the tubing string and maintain its stability when clamping the upper pipe.

[0038] When the lower tubing is positioned between the two standby clamp teeth, the output end of the standby clamp cylinder 431 pushes the standby clamp teeth, bringing the two opposing standby clamp teeth closer together and clamping the tubing string. The standby clamp teeth are generally arc-shaped, allowing them to fit snugly against the tubing string and maintain its stability when clamping the upper tubing.

[0039] In existing iron drill 400 systems, the main clamp 410 and the rotary mechanism 420 are mostly rigidly connected. During the uncoupling process, the distance between the upper pipe and the lower oil pipe will change as the threads of the tubing string are tightened or loosened. The rigid connection between the main clamp 410 and the rotary mechanism 420 lacks an adjustment and compensation device, which can easily cause damage to the tubing string. Furthermore, if the main clamp 410 clamps the upper pipe, there may be an angular deviation when the upper pipe and the lower oil pipe are aligned, which can also easily cause damage to the tubing string joint.

[0040] Preferably, in order to solve the problem caused by the rigid connection between the main clamp 410 and the rotary mechanism 420, the main clamp 410 and the rotary mechanism 420 of the iron drill 400 in this embodiment are connected by an elastic component.

[0041] See Figure 2 Mounting ears 414 are provided at positions corresponding to the elastic components on the first mounting housing 412. Four mounting ears 414 are installed around the perimeter of the rectangular first mounting housing 412. The elastic component includes a slide rod 401 and a helical spring 402 sleeved on the slide rod 401. The slide rod 401, located on the same side of the first mounting housing 412, is connected to the same connecting rod 403. After passing through the mounting ears 414, the upper end of the slide rod 401 is fixedly connected to the connecting rod 403, and the lower end of the slide rod 401 is fixedly connected to the upper surface of the rotary mechanism 420; one end of the helical spring 402 abuts against the lower surface of the mounting ear 414, and the other end of the helical spring 402 abuts against the upper surface of the rotary mechanism 420. Preferably, the slide bar 401 passes through the mounting ear 414, which provides precise linear guidance, ensuring that the main clamp 410 can move along a predetermined vertical path during distance adjustment, avoiding lateral displacement and improving motion accuracy. A helical spring 402 is used as the elastic element, and its elastic coefficient can be selected according to different specifications of tubing and working conditions. By replacing springs with different stiffnesses, the magnitude of the compensation force can be flexibly adjusted to adapt to various operating conditions. Four elastic components are used, which can be evenly distributed around the first mounting housing 412. Each elastic component works independently, ensuring that the main clamp 410 is subjected to uniform force, moves smoothly, and improves working stability.

[0042] The slide bar 401 located on the same side of the first mounting housing 412 is connected to the same connecting rod 403, so that the two elastic components on the same side form a linkage mechanism, which maintains synchronous and approximately equal movement during compression, so that the main clamp 410 can maintain good balance during adjustment and avoid tilting or twisting. The introduction of the connecting rod 403 can also form a rigid frame structure on both sides of the first mounting housing 412, which enhances the overall rigidity of the main clamp 410 and can remain stable even under lateral force, which helps to prevent the main clamp 410 from unexpected lateral displacement during operation.

[0043] Preferably, the main clamp 410 is mounted on the first mounting housing 412 and elastically connected to the rotary mechanism 420 via four elastic components. These elastic components act as stroke compensation devices, compensating for distance changes caused by tightening or loosening of the tubing threads during the clamping and unclamping process. The elastic components also provide necessary buffering, allowing the driller 400 to flexibly adapt to changes in the distance between the upper tubing and the lower tubing. Furthermore, the design using four elastic components not only provides vertical adjustment capability but also accommodates angular deviations in the horizontal plane to a certain extent. When the main clamp 410 clamps the upper tubing, if the upper tubing and the lower tubing are not coaxial and have angular deviations, these elastic components can provide minor angular adjustments to help better align the tubing. This driller 400 cleverly solves various problems caused by the rigid connection between the main clamp 410 and the rotary mechanism 420 by incorporating elastic components, not only improving the adaptability and operational efficiency of the equipment but also significantly reducing the risk of tubing damage and enhancing the safety and reliability of live well workover operations.

[0044] See Figure 2 Because oil and gas field environments often contain pollutants such as mud, rock cuttings, and oil, an overflow cavity is installed inside the second mounting housing. The overflow cavity design provides a discharge channel for these pollutants. For example, it can prevent wastewater from the oil pipe from spraying onto the platform when the oil pipe is being retrieved, keeping the driller clean and contributing to environmental protection in the oil field.

[0045] Preferably, an observation window and a door panel are provided on one side of the second mounting housing. The door panel is hinged to the second mounting housing, and the observation window is closed when the door panel is closed. The door panel is equipped with a push rod, which is used to open or close the door panel. Specifically, the push rod can be a hydraulic cylinder, oil cylinder, or pneumatic cylinder, etc.

[0046] Preferably, the door panel and observation window together provide direct access to the interior of the second mounting housing. Workers can open the door panel and directly clean accumulated mud, rock debris, and other contaminants through the observation window, maintaining internal cleanliness and extending the equipment's lifespan. When the spare clamp 430 or the internal piping of the second mounting housing requires maintenance, technicians can directly open the door panel on-site for quick component replacement, minimizing downtime.

[0047] Preferably, during the upper clamping operation, the control unit 100 first determines, via the camera 210, whether the upper and lower pipes have been properly clamped. If the clamping is complete, the control unit 100 controls the main clamp 410 and the backup clamp 430 to clamp the oil pipe via the hydraulic adjustment unit 300. With the main clamp 410 clamping the upper pipe and the backup clamp 430 clamping the lower pipe, the control unit 100 controls the hydraulic motor 421 via the hydraulic adjustment unit 300 to cause the rotary mechanism 420 to drive the main clamp 410 to rotate in the first direction until the upper clamping is complete.

[0048] Preferably, during the uncoupling operation, the control unit 100 first controls the main clamp 410 and the backup clamp 430 to clamp the oil pipe via the hydraulic adjustment unit 300. With the main clamp 410 clamping the upper pipe and the backup clamp 430 clamping the lower pipe, the control unit 100 controls the hydraulic motor 421 to rotate in the second direction via the hydraulic adjustment unit 300. The control unit 100 determines whether the upper and lower pipes are separated via the camera 210; if the upper and lower pipes are separated, the uncoupling is complete.

[0049] The second direction is the opposite of the first direction. The first direction is the direction to tighten the upper pipe and the lower pipe, and the second direction is the direction to untie the upper pipe and the lower pipe.

[0050] Preferably, the control unit 100 includes a display screen, a data processor, and an input module. The data processor is electrically connected to the display screen, the input module, the monitoring unit 200, and the hydraulic adjustment unit 300. Data collected by the monitoring unit 200 is processed by the data processor and then transmitted to the display screen for display. Hydraulic parameters of the power component are processed by the data processor and then transmitted to the display screen for display. The data processor generates control commands based on the data sent by the input module and sends the control commands to the hydraulic adjustment unit 300 to control the operating status of the iron drill 400.

[0051] Example 3

[0052] This embodiment provides a live-line working device. See also... Figure 3The live-line working equipment includes a powered catwalk 501, a pipe lifting system 502, a live-line working machine 503, a platform robotic arm 504, and a ground robotic arm 505. The powered catwalk 501 is located on one side of the live-line working machine 503. The ground robotic arm 505 is located between the powered catwalk 501 and the live-line working machine 503. The platform robotic arm 504 is located on the top platform of the live-line working machine 503. The pipe lifting system 502 is used to transport the oil pipe between the powered catwalk 501 and the live-line working machine 503. During the pipe lifting process, the platform robotic arm 504 and the ground robotic arm 505 use their robotic arms to straighten the oil pipe, preventing it from bumping against the live-line working machine 503. The live-line working equipment also includes the remote pipe coupling and uncoupling control system for live-line working described in Embodiments 1 and 2, wherein the iron drill 400 is installed on the live-line working machine 503.

[0053] When the live-line working equipment provided in this embodiment performs pipe coupling and uncoupling operations, the remote pipe coupling and uncoupling control system for live-line working uses the monitoring unit 200 to monitor the working status of the iron drill 400 in real time, and sends control commands to the hydraulic adjustment unit 300 through the control unit 100. The hydraulic adjustment unit 300 adjusts the hydraulic oil supply of each power component in the iron drill 400 according to the control commands, thereby controlling the working status of the iron drill 400 to complete the coupling and uncoupling operations of the pipe joint.

[0054] The control unit 100 and the hydraulic adjustment unit 300 remotely control the iron drill 400 to perform the coupling and uncoupling operations of the oil pipe joints. This eliminates the need for workers to directly contact the high-pressure environment, avoids exposing workers to potential dangers, reduces the risk of injury, and ensures the safety of the coupling and uncoupling operations of the oil pipe joints.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
