Description

Technical Field

[0001] This utility model relates to the field of gas well operations, and in particular to a remote-controlled gas well pressurized operation equipment and its remote control system. Background Technology

[0002] In the development of oil and gas fields, the operation of pipe fittings—including transportation, hoisting, installation, and connection—is a crucial link. Traditional pipe fitting operations usually require workers to manually operate these heavy pipe fittings in complex environments such as high altitudes or offshore platforms. This is not only inefficient, but also greatly increases the risk of personnel injury under high-pressure environments or extreme weather conditions.

[0003] To improve this situation and ensure employee safety, the introduction of advanced remote control technology is crucial. Using intelligent remote control systems to perform pipework operations significantly reduces the need for direct exposure to hazardous environments. Remote control systems allow operators to precisely direct field equipment from a secure control room or even a remote office, effectively preventing accidents caused by human error and improving overall work efficiency.

[0004] Using remote control technology for pipework operations can not only greatly enhance operational safety, but also promote the sustainable development of the oil and gas extraction industry.

[0005] For example, utility model patent CN209025645U provides a remote control system for a high-pressure manifold used in cementing operations. This system includes a remote PLC controller, a hydraulic subsystem, and at least one hydraulically controlled plug valve and at least one hydraulically controlled needle valve arranged at corresponding control points on the high-pressure manifold. The hydraulically controlled plug valve has a plug valve controller that maintains real-time communication with the remote PLC controller, and the hydraulically controlled needle valve has a needle valve controller that maintains real-time communication with the remote PLC controller. The hydraulic subsystem is used to provide hydraulic power to the hydraulically controlled plug valve and the hydraulically controlled needle valve respectively. The hydraulic subsystem's action of providing hydraulic power to the hydraulically controlled plug valve is controlled by the plug valve controller, and the hydraulic subsystem's action of providing hydraulic power to the hydraulically controlled needle valve is controlled by the needle valve controller.

Preferably, the remote control center 800 is equipped with several detection devices 900 for collecting live-line operation data and the working data of the wellhead device 200, the powered catwalk 300, the lifting device 400, the ground robot 500, and the platform robot 600.

[0068] Preferably, a flared opening 212 is located in the middle of the flared opening 211 and is used to guide the suspended tubing during the coupling process. Preferably, the flared opening 212 is made of a soft material such as rubber to prevent damage to the tubing from impacts. The flared opening 212 is connected to the flared opening 211 via a slider 214, and the flared opening 212 slides along the edge of the flared opening 211 via the slider 214. The slider 214 is connected to the fourth telescopic rods 213 located at both ends of the flared opening 211; and the fourth telescopic rods 213 are connected to the remote control center 800 via data connection. Preferably, the guiding device 300 is located at the wellhead via the flared opening 211, and the remote control center 800 adjusts the position of the flared opening 212 on the flared opening 211 by controlling the extension and retraction of the fourth telescopic rods 213. The flared opening 212 is hollow and has a through-hole interior, with its bottom screwed to the slider 214. Preferably, slide rails are provided on both sides of the flared opening 211 where the fourth telescopic rods 213 are not located. The slider 214 moves horizontally along the slide rails. Preferably, the center of the flared opening 211 is hollowed out, and the lifting device 400 suspends and lowers the tubing, which passes through the flared opening 212 and connects with the tubing in the well. The size of the hollowed-out area in the center of the mounting plate 210 meets the condition that the bottom opening of the flared opening 212 is not obstructed when the slider 214 is at its limit stroke. Preferably, the flared opening 212 can be configured with different sizes to accommodate different specifications of tubing, or it can be set to a fixed size that can accommodate different specifications of tubing.

[0069] See Figure 8 The iron drill 220 includes: a main clamp 221, a rotary mechanism 222, a spare clamp 223, a first hydraulic cylinder 224, a first hydraulic motor 225, a second hydraulic cylinder 226, a first housing 227, a through hole 228, a second housing 229, a mounting lug 230, a slide rod 231, a coil spring 232, and a connecting rod 233.

[0070] Preferably, the wellhead device 200 further includes a steel drill 220. The steel drill 220 includes a main clamp 221, a rotating mechanism 222, and a backup clamp 223. The main clamp 221 is used to clamp the upper pipeline. The power component of the main clamp 221 is configured as a first hydraulic cylinder 224. The rotating mechanism 222 is used to drive the main clamp 221 to rotate. The power component of the rotating mechanism 222 is configured as a first hydraulic motor 225. The backup clamp 223 is used to clamp the lower pipeline. The power component of the backup clamp 223 is configured as a second hydraulic cylinder 226.

[0071] See Figure 8 Preferably, the main clamp 221 is positioned above the rotary mechanism 222, and the backup clamp 223 is positioned below the rotary mechanism 222. The backup clamp 223 is closer to the wellbore, while the main clamp 221 is farther from the wellbore. The rotary mechanism 222 is positioned between the main clamp 221 and the backup clamp 223. The power assembly of the iron drill 220 also includes a first hydraulic cylinder 224 configured in the main clamp 221 and a second hydraulic cylinder 226 configured in the backup clamp 223. The first hydraulic cylinder 224, the first hydraulic motor 225, and the second hydraulic cylinder 226 are respectively connected to the hydraulic power source 700 via hydraulic lines.

[0072] The main clamp 221 is equipped with a first housing 227, which is elastically connected to the rotary mechanism 222 via four elastic components. The backup clamp 223 is equipped with a second housing 229, which is fixedly connected to the rotary mechanism 222.

[0073] See Figure 8 The first housing 227 can be a cuboid structure with six openings on each side. The first housing 227 is as follows: Figure 2 A through hole 228 is provided in the vertical direction (up and down direction) for the oil supply pipe to pass through. A guide assembly 210 is installed on the side of the through hole 228 away from the rotating mechanism 222. Preferably, the guide assembly 210 is installed on the side of the through hole 228 away from the rotating mechanism 222 via a mounting plate 211, and the flared end 212 overlaps with the through hole 228 when guiding the oil pipe.

[0074] When the upper pipe enters the iron drill 220, the upper pipe first passes through the guide component 210, which guides the upper pipe into the correct axis to achieve pre-alignment and reduce the difficulty of subsequent clamping. Since the upper pipe has been pre-aligned by the stabilizer, the main clamp 221 can clamp the pipe string faster and more accurately, thereby improving the clamping efficiency of the main clamp 221 and speeding up the entire coupling process.

[0075] The main clamp 221 is equipped with two main clamp teeth, which are respectively installed on the left and right sides of the first housing 227, and are positioned opposite each other. Each main clamp tooth is equipped with a first hydraulic cylinder 224. The output end of the first hydraulic cylinder 224 is connected to the main clamp tooth. When the upper pipeline is located between the two main clamp teeth, the output end of the first hydraulic cylinder 224 pushes the main clamp teeth, bringing the two opposing main clamp teeth closer together and clamping the pipeline. The main clamp teeth are generally arc-shaped, allowing them to conform to the pipeline and maintain its stability when clamping the upper pipeline.

[0076] Preferably, the rotary mechanism 222 is a hydraulic rotary mechanism (also known as a hydraulic rotary transmission device), which includes a first hydraulic motor 225, a brake, a reducer, a valve group, a gear end structure, etc. This hydraulic rotary mechanism can adjust its torque and speed by adjusting the hydraulic parameters (such as pressure, flow rate, flow direction, etc.) of the first hydraulic motor 225. Preferably, the rotary mechanism 222 is a hydraulic rotary mechanism, which can provide more powerful torque, enabling the drill bit 220 to easily handle high-strength, large-size pipe string connections.

[0077] In existing iron drill 220s, the main clamp 221 and the rotary mechanism 222 are mostly rigidly connected. During the uncoupling process, the distance between the upper pipe and the lower oil pipe will change as the threaded joints are tightened or loosened. The rigid connection between the main clamp 221 and the rotary mechanism 222 lacks an adjustment and compensation device, which can easily cause damage to the tubing. Furthermore, if the main clamp 221 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 joints of the tubing.

[0078] Preferably, in order to solve the problem caused by the rigid connection between the main clamp 221 and the rotary mechanism 222, the main clamp 221 and the rotary mechanism 222 of the iron drill 220 in this embodiment are connected by an elastic component.

[0079] See Figure 8 Mounting ears 230 are provided at the positions corresponding to the elastic components on the first housing 227. Four mounting ears 230 are installed around the perimeter of the cuboid-shaped first housing 227.

[0080] See Figure 8 The elastic component includes a slide rod 231 and a helical spring 232 sleeved on the slide rod 231. The slide rod 231, located on the same side of the first housing 227, is connected to the same connecting rod 233. See also Figure 2 After the slide rod 231 passes through the mounting ear 230, the upper end of the slide rod 231 is fixedly connected to the connecting rod 233, and the lower end of the slide rod 231 is fixedly connected to the upper surface of the rotary mechanism 222; one end of the helical spring 232 abuts against the lower surface of the mounting ear 230, and the other end of the helical spring 232 abuts against the upper surface of the rotary mechanism 222.

[0081] Preferably, the slide bar 231 passes through the mounting ear 230, which provides precise linear guidance, ensuring that the main clamp 221 can move along a predetermined vertical path during distance adjustment, avoiding lateral displacement and improving motion accuracy. A helical spring 232 is used as the elastic element, and its elastic coefficient can be selected according to different specifications of the 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 housing 227. Each elastic component works independently, ensuring that the main clamp 221 is subjected to uniform force, moves smoothly, and improves working stability.

[0082] The slide bar 231 located on the same side of the first housing 227 is connected to the same connecting rod 233, 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 221 can maintain good balance during adjustment and avoid tilting or twisting. The introduction of the connecting rod 233 can also form a rigid frame structure on both sides of the first housing 227, which enhances the overall rigidity of the main clamp 221 and can remain stable even under lateral force, which helps to prevent the main clamp 221 from unexpected lateral displacement during operation.

[0083] Preferably, the main clamp 221 is mounted on the first housing 227 and elastically connected to the rotary mechanism 222 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 drill bit 220 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 221 clamps the upper tubing, if the upper tubing and the lower tubing are not aligned or have angular deviations, these elastic components can provide minor angular adjustments to help better align the tubing. This drill bit 220 cleverly solves various problems caused by the rigid connection between the main clamp 221 and the rotary mechanism 222 by incorporating elastic components, improving the adaptability and operational efficiency of the equipment, significantly reducing the risk of tubing damage, and enhancing the safety and reliability of live well workover operations.

[0084] See Figure 8 Because oil and gas field environments often contain pollutants such as mud, rock cuttings, and oil, an overflow cavity is provided inside the second shell 229. 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.

[0085] See Figure 8 The spare clamp 223 is equipped with two spare clamp teeth, which are respectively installed on the left and right sides of the second housing 229, and are positioned opposite each other. Each spare clamp tooth is equipped with a second hydraulic cylinder 226. The output end of the second hydraulic cylinder 226 is connected to the spare clamp tooth. When the lower oil pipe is located between the two spare clamp teeth, the output end of the second hydraulic cylinder 226 pushes the spare clamp teeth, bringing the two opposing spare clamp teeth closer together and clamping the tubing string. The spare clamp teeth are generally arc-shaped, which allows them to conform to the tubing string and maintain its stability when clamping the upper pipe.

[0086] Furthermore, an observation window and a door panel are provided on one side of the second housing 229. The door panel is hinged to the second housing 229, and the observation window is closed when the door panel is closed. A push rod is installed on the second housing 229, 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.

[0087] Preferably, the door panel and the observation window together provide direct access to the interior of the second housing 229. 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 223 or the internal piping of the second housing 229 requires maintenance, technicians can directly open the door panel on-site for quick component replacement, reducing downtime.

[0088] Preferably, the detection device 900 includes an encoder 910, a pressure sensor 920, and a camera 930. The encoder 910 includes a first encoder, a second encoder, and a third encoder. The first encoder is configured on the rotary mechanism 222 and is used to acquire the number of rotations and the rotational speed of the rotary mechanism 222. The second encoder is configured on the slipper 330 and is used to acquire the traveling distance and traveling speed of the slipper 330. The third encoder is configured on the winch 420 and is used to acquire the winding speed and distance of the winch 420 on the traction cable 103.

[0089] Preferably, a first encoder is mounted on the first hydraulic motor 225 of the rotary mechanism 222 and is connected to the remote control center 800 via data connection. The first encoder is used to monitor information such as the rotational speed and shaft position of the first hydraulic motor 225 in real time. The remote control center 800 can determine the number of rotations and rotational speed of the rotary mechanism 222 based on the monitoring data from the first encoder. The hydraulic power source 700 can control the rotational speed and direction of rotation of the first hydraulic motor 225 by adjusting its hydraulic parameters, thereby controlling the rotational speed and direction of rotation of the main clamp 221 driven by the rotary mechanism 222.

[0090] Preferably, the second encoder is mounted on the second hydraulic motor of the slipper 330 and is connected to the remote control center 800 via data connection. The second encoder is used to monitor information such as the rotational speed and shaft position of the second hydraulic motor in real time. The remote control center 800 can determine the position, speed, and direction of movement of the slipper 330 based on the parameters monitored by the second encoder, and thus regulate the slipper 330.

[0091] Preferably, the winch 420 is equipped with a third hydraulic motor, which is connected to one end of the traction cable 103. A third encoder is mounted on the third hydraulic motor and is connected to the remote control center 800. The third encoder is used to monitor the speed and shaft position of the third hydraulic motor in real time. The remote control center 800 can determine the status of the third hydraulic motor based on the parameters monitored by the third encoder and then regulate it. The remote control center 800 controls the rotation direction and speed of the third hydraulic motor to raise and lower the traction cable 103, thereby causing the traveling block 410 to rise or fall.

[0092] A pressure sensor 920 is mounted on the power assembly of the working device to acquire hydraulic parameters of the power assembly. Preferably, the hydraulic parameters include hydraulic pressure, flow rate, and flow direction.

[0093] Preferably, the power assembly of the wellhead device 200 includes: a fourth hydraulic telescopic rod 213 of the guide assembly 210; a first hydraulic cylinder 224, a first hydraulic motor 225, and a second hydraulic cylinder 226 of the drill bit 220. Preferably, the remote control center 800 adjusts the position of the bell mouth 212 by controlling the hydraulic parameters of the fourth hydraulic telescopic rod 213. Preferably, the remote control center 800 controls the clamping or loosening of the main clamp 221 by controlling the hydraulic parameters of the first hydraulic cylinder 224. Preferably, the remote control center 800 controls the rotational speed and direction of rotation of the main clamp 221 driven by the rotary mechanism 222 by controlling the hydraulic parameters of the first hydraulic motor 225. Preferably, the remote control center 800 controls the clamping or loosening of the spare clamp 223 by controlling the hydraulic parameters of the second hydraulic cylinder 226.

[0094] Preferably, the power component of the power catwalk 300 is a second hydraulic motor. Preferably, the remote control center 800 controls the moving speed and direction of the sliding shoe 330 by controlling the hydraulic parameters of the second hydraulic motor.

[0095] Preferably, the power components of the lifting device 400 include: a first hydraulic telescopic rod 414 of the traveling trolley 410 and a third hydraulic motor of the winch 420. Preferably, the remote control center 800 adjusts the swing angle of the first swing arm 412 of the traveling trolley 410 by controlling the hydraulic parameters of the first hydraulic telescopic rod 414. Preferably, the remote control center 800 controls the rotation direction and speed of the third hydraulic motor by controlling the hydraulic parameters of the third hydraulic motor to achieve the winding and unwinding of the traction cable 103.

[0096] Preferably, the power component of the ground robot 500 is the second hydraulic telescopic rod 530. Preferably, the remote control center 800 adjusts the swing angle of the second swing arm 520 of the ground robot 500 by controlling the hydraulic parameters of the second hydraulic telescopic rod 530.

[0097] Preferably, the power component of the tabletop robot 600 is a third hydraulic telescopic rod 630. Preferably, the remote control center 800 adjusts the swing angle of the third swing arm 620 of the tabletop robot 600 by controlling the hydraulic parameters of the third hydraulic telescopic rod 630.

[0098] Preferably, the hydraulic power source 700 is equipped with several electronic valves, which can regulate parameters such as the delivery pressure, flow rate, and flow direction of the hydraulic oil. The hydraulic power source 700 can control the hydraulic parameters of each power component through the electronic valves. Preferably, the electronic valves and power components are equipped with sensors such as pressure gauges and flow meters that can detect hydraulic parameters, and these sensors are connected to the remote control center 800, enabling the remote control center 800 to acquire the hydraulic parameters of the power components.

[0099] Camera 930 is used to capture images of remotely controlled gas well pressurized operation equipment and its various working devices.

[0100] Preferably, the data connection between the testing device 900 and the remote control center 800 adopts the Ethernet communication protocol, including both wireless and wired communication methods, and the two communication methods serve as backups for each other.

[0101] Preferably, the remote control center 800 is equipped with a display screen, a data processor, and an input module. The data processor is connected to the display screen, the input module, the detection device 900, and the remote control center 800. Data collected by the detection device 900 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 power source 700 to control the operating status of the corresponding working device.

[0102] Preferably, the pressurized operation includes at least the following: tubing lifting operation, which transports the tubing from the power catwalk 300 to the working platform 100; coupling operation, which lowers the tubing into the well; and the third operation, which performs a screw-coupling operation to complete the coupling of the tubing.

[0103] Preferably, when performing tubing lifting operations, the remote control method includes the following steps:

[0104] S11. Clamping the oil pipe. The remote control center 800 controls the rotation of the winch 420 to bring the traveling car 410 closer to the power catwalk 300, so that the clamp 411 mounted on the traveling car 410 can clamp the oil pipe placed on the transport track 320. The clamp 411 clamps one end of the oil pipe. Preferably, when the clamp 411 reaches the transport track 320, the remote control center 800 controls the slipper 330 to push the oil pipe on the transport track 320, so that one end of the oil pipe enters the clamping range of the clamp 411.

[0105] S12. Confirm successful tubing clamping. The remote control center 800 can confirm whether the clamp 411 has successfully clamped the tubing using images captured by the camera 930 or parameters from the second encoder. If the clamp 411 has successfully clamped the tubing, proceed to step S13. Confirmation can be made by checking whether one end of the tubing has entered the clamp 411 using images captured by the camera 930, or by checking whether the sliding shoe 330 has moved a sufficient distance to push one end of the tubing into the clamp 411 using parameters from the second encoder.

[0106] S13. The hydraulic pipe is lifted. After confirming that the clamp 411 has successfully gripped the hydraulic pipe, the remote control center 800 controls the rotation of the winch 420 to move the traveling block 410 away from the power catwalk 300, causing the hydraulic pipe to rise and begin to detach from the transport track 320. Specifically, the remote control center 800 sends a command to the winch 420, causing it to rotate and retrieve the traction cable, thereby lifting the traveling block 410 and the hydraulic pipe. During the process of the traveling block 410 lifting the hydraulic pipe, the end of the hydraulic pipe connected to the clamp 411 detaches from the transport track 320 first, while the end of the hydraulic pipe not connected to the clamp 411 gradually approaches the work platform 100 under the push of the slipper 330 until it detaches from the transport track 320.

[0107] S14. Initial pipe support. When the traveling trolley 410 leaves the rotation range of the ground manipulator 500 and the end of the oil pipe not connected to the jack 411 has not left the transport track 320, the remote control center 800 controls the ground manipulator 500 to rotate, so that the ground manipulator 500 supports the oil pipe.

[0108] The remote control center 800 can determine the separation status of the oil pipe from the transport track 320 by using images from the camera 930 and the length of the traction cable retrieved by the winch 420. When the traveling trolley 410 leaves the rotation range of the ground manipulator 500 and the end of the oil pipe not connected to the hoist 411 is still on the catwalk, the remote control center 800 controls the ground manipulator 500 to rotate, thus supporting the oil pipe. Specifically, the remote control center 800 adjusts the hydraulic parameters of the second hydraulic telescopic rod 530 via the hydraulic power source 700, causing the second hydraulic telescopic rod 530 to extend and retract, driving the second swing arm 520 to swing around the first base 510, away from the work platform 100. This allows the first guide wheel 540 to contact the oil pipe, ensuring that the oil pipe moves along the first guide wheel 540 during its ascent. This prevents the oil pipe from swaying due to changes in force when separating from the catwalk, and thus avoids a collision between the oil pipe and the work platform 100 when separating from the transport track 320.

[0109] S15. Secondary pipe support. When the traveling carriage 410 leaves the rotation range of the platform robot 600, the remote control center 800 controls the rotation of the platform robot 600, so that the platform robot 600 supports the oil pipe.

[0110] The remote control center 800 determines the lifting status of the oil pipe using images captured by the camera 930 and the length of the traction cable retrieved by the winch 420. When the traveling trolley 410 leaves the rotation range of the platform robot 600 and the end of the oil pipe not connected to the lifting clamp remains on the guide roller, the remote control center 800 controls the platform robot 600 to rotate, thus supporting the oil pipe. Specifically, the remote control center 800 adjusts the hydraulic parameters of the third telescopic rod 630 via the hydraulic power source 700, causing the third telescopic rod 630 to extend and retract, driving the third swing arm 620 to swing around the second base 610. This ensures that the second guide wheel 640 contacts the oil pipe, guaranteeing that the oil pipe moves along the second guide wheel 640 during the ascent, thereby preventing the oil pipe from colliding with the work platform 100 after detaching from the first guide wheel 540 or the guide rollers on the work platform 100.

[0111] When the oil pipe is short or the working platform 100 is high, the working platform 100 can be additionally equipped with several guide rollers. During the oil pipe's ascent, the remote control center 800 controls the ground robot 500 to rotate and approach the working platform 100. After the oil pipe detaches from the first guide wheel 540, the guide rollers on the working platform 100 can continue to guide the oil pipe, preventing collisions between the oil pipe and the working platform 100. Preferably, the guide rollers on the working platform 100 and the first guide wheel 540 of the ground robot 500 are on the same plane.

[0112] Preferably, during the coupling operation, the remote control center 800 adjusts the swing angle of the first swing arm 412 by controlling the extension and retraction of the first hydraulic telescopic rod 414, and adjusts the swing angle of the third swing arm 620 by controlling the extension and retraction of the third hydraulic telescopic rod 630, so that the tubing is vertical and aligned with the wellhead. Preferably, when the first swing arm 412 swings to a specific angle and the third swing arm 620 rotates to a specific angle, the suspended tubing is in a vertical state or tends to be vertical under the action of gravity.

[0113] During the coupling operation, the remote control center 800 adjusts the swing angle of the third swing arm 620 by controlling the extension and retraction of the third hydraulic telescopic rod 630, so that the second guide wheel 640 contacts the oil pipe to provide a force point for the oil pipe and prevent the oil pipe from shaking. Preferably, during the coupling operation, the third swing arm 620 rotates towards the support rod 102, so that the guide roller 240 contacts the rising oil pipe to provide a force point for the oil pipe and prevent the oil pipe from shaking.

[0114] Preferably, the remote control center 800 adjusts the swing angle of the third swing arm 620 by controlling the extension and retraction of the third hydraulic telescopic rod 630, so that the second guide wheel 640 always contacts the oil pipe during the oil pipe lifting and coupling operation to provide a force point for the oil pipe and prevent the oil pipe from shaking.

[0115] Preferably, the remote control center 800 adjusts the length of the telescopic rod based on the pressure sensor data configured on the hydraulic telescopic rod, thereby adjusting the swing angle of the first swing arm 412, the swing angle of the third swing arm 620, and the position of the horn mouth 320.

[0116] The remote control center 800 uses images captured by the camera 930 to confirm whether the oil pipe is close to the flare 212; if the oil pipe is close to the flare 212, the remote control center 800 controls the fourth hydraulic telescopic rod 213 to align the flare 212 with the descending oil pipe.

[0117] Preferably, when performing the screw-on operation, the remote control method includes the following steps:

[0118] S21. Determine if the coupling is successful. Determine if the upper and lower pipes have successfully coupled; if the coupling is successful, proceed to step S12. The remote control center 800 first determines whether the upper and lower pipes have successfully coupled by using the image captured by the camera 930.

[0119] S22, Clamping the pipe. The remote control center 800 controls the main clamp 221 and the backup clamp 223 to clamp the oil pipe via the hydraulic power source 700. The main clamp 221 clamps the upper pipe, and the backup clamp 223 clamps the lower pipe.

[0120] S23, Turning. The remote control center 800 controls the first hydraulic motor 225 to rotate via the hydraulic power source 700 until the turning is completed.

[0121] S24. Loosen the pipe. The remote control center 800 controls the main clamp 221 to loosen the upper pipe and the backup clamp 223 to loosen the lower pipe via the hydraulic power source 700.
