Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oil and gas well exploitation, and in particular to a fully automatic vertical pipe laying device, a pipe laying mechanical arm, a pipe laying rack and related methods for lifting and lowering pipe strings during minor repair operations. Background Art
[0002] In the process of oil and gas well exploitation, downhole operations are important to maintain the daily production of oil, gas and water wells. Among them, the volume of minor repair operations such as oilfield pump inspection and tubing string lifting is large, accounting for more than half of the total volume of downhole operations. At present, minor repair operations can realize automatic operations such as automatic buckling and unbuckling of oil pipes and automatic pipe removal. For example, the flat-laying conveying device disclosed in the invention patent with publication number CN106401505B and its conveying method for an automatic conveying device for oil pipe rods in well repair operations can realize the automatic transportation of oil pipes. Summary of the invention
[0003] The inventor of the present application has found that due to the thin diameter of the sucker rod, it is easy to bend and deform when laid flat on the pipe rack, and it is also easy to bend and deform the sucker rod during transportation from the wellhead to the pipe rack. Therefore, the existing automatic pipe transportation and pipe arrangement operation device cannot realize the automatic operation of the sucker rod. Moreover, the automatic pipe operation device has a low degree of automation and occupies a large area. When used, the conveyor pick-up and delivery mechanism must be directly opposite the wellhead for well repair, resulting in the need to call a crane during on-site installation, which is complicated and time-consuming to install, and difficult to discharge on-site when applied to cluster wells. In short, the existing automatic pipe arrangement technology for minor repair operations is still not mature enough, the degree of automation is still relatively low, and the labor intensity of on-site operators in the oil field is relatively high. Improving the degree of automatic pipe arrangement operation for minor repair operations is the most urgent technical problem to be solved in the automation technology for minor repair operations.

[0123] The pipe rack of the pipe racking device provided in the embodiment of the present invention has a retractable leg with adjustable height. The legs are fully retracted during transportation. After arriving at the destination, the legs are extended to support the ground, so that the pipe rack can be automatically lifted off the transport vehicle to achieve automatic unloading. When transportation is required, the transport vehicle enters the lower part of the pipe rack, and the legs are fully retracted to achieve self-loading. In the case of no crane, the pipe rack can be automatically loaded and unloaded. At the same time, the oil pipe can be limited by multiple oil pipe limiting structures arranged on the oil pipe rack. One end of the oil pipe is placed on the ground and the other end is limited by the oil pipe limiting structure to achieve vertical discharge of the oil pipe; the multiple sucker rod hanging structures on the sucker rod rack can hang the sucker rod, so that the sucker rod can be vertically discharged on the sucker rod rack in a hanging manner.
[0124] Both the tubing rack and the sucker rod rack are equipped with a lifting structure. During transportation, the overall height of the tubing rack and the sucker rod rack is lowered to meet transportation requirements. During operation, the height of the tubing rack and the sucker rod rack is raised to meet operation requirements, thereby realizing the fully automatic pipe laying operation of the tubing and the sucker rod conveniently and quickly.
[0125] Optionally, in the above-mentioned device, power control units can be independently set for the mechanical arm 1 and the pipe rack 2. Considering the rationality of the entire device, the hydraulic power source and the electrical and hydraulic control system of the fully automatic vertical pipe racking device can also be integrated on the pipe rack, that is, set as a common power control unit. The common power control unit can be installed on the base frame 21 of the pipe rack 2. In the above-mentioned fully automatic vertical pipe racking device, the mechanical arm can be installed on the pipe rack and transported and installed together with the pipe rack, so as to achieve convenient and fast automated installation and debugging, reduce manual operations, reduce the intensity of personnel work, and improve the level of automation. Through the cooperation of the mechanical arm and the pipe rack, the automatic movement of the oil pipe and the sucker rod during the process of grabbing, transporting, discharging the pipe rack from the wellhead, grabbing, transporting, and lowering the pipe rack from the wellhead can be realized, and fully automated operations can be realized without reducing the number of on-site operators, thereby improving the efficiency of well repair and pipe laying operations.
[0126] Each part of the skid-mounted fully automatic vertical pipe laying device can be folded, lifted, and compressed to meet the transportation restrictions of road transportation. After the equipment is transported to the site, each part can be opened, lifted, and quickly assembled to form an operational state. The device is designed to be electrically driven, and the power is taken from the wellhead power distribution system on the oil field site, or mobile power supply facilities are used. The skid-mounted fully automatic vertical pipe laying device meets the on-site requirements of single well and cluster well operations. For cluster well operation scenarios, please refer to Figure 7a and Figure 7b As shown. A plurality of pumping units 6 are arranged at a plurality of production wellheads 7. When one of the production wellheads 7 needs to be repaired, a workover machine 8 is placed at the production wellhead to be repaired. The pipe arrangement device including the mechanical arm 1 and the pipe arrangement rack 2 can be unloaded from the transport vehicle 5 and installed at the production wellhead to be repaired. It can be conveniently placed at any wellhead to be repaired, facilitating automated operations.
[0127] The robot arm 1 can be hydraulically driven, and can realize a series of precise actions of the robot arm such as fully automatic pipe grabbing, pipe transportation, pipe arrangement, pipe placement, and pipe removal through electro-hydraulic proportional, servo and other control and intelligent detection methods.
[0128] During transportation, the legs of the pipe rack 2 are fully retracted, and the lifting structures of the oil pipe support and the sucker rod support are fully retracted to meet the requirements of road transportation conditions, and the pipe rack can be transported by the transport vehicle 5. The legs of the pipe rack 2 can be extended. When arriving at the work site, the legs are extended to both sides beyond the width of the transport vehicle, and the leg cylinders are extended downward, and the legs are supported on the ground, and the pipe rack is lifted off the transport vehicle. The transport vehicle can freely enter and exit the lower part of the pipe rack, and the pipe rack can be automatically loaded and unloaded without the need for a crane.
[0129] The pipe rack 2 can realize the lifting and lowering of the oil pipe limiter and the sucker rod limiter by extending and retracting the lifting frame. When the lifting frame is retracted, the size of the pipe rack meets the requirements of road transportation. When the lifting frame is extended, the pipe rack is in a working state and can perform automated pipe laying operations.
[0130] When the fully automatic vertical pipe laying device needs to be transported, the transportation status of its mechanical arm can be found in Figure 5a-5d As shown, the telescopic mechanism is controlled to retract the gripper mechanism, the slewing mechanism is controlled to rotate the lifting column so that the telescopic mechanism and the gripper mechanism are at an angle suitable for transportation, the lifting mechanism is controlled to lower the telescopic mechanism and the gripper mechanism to a height suitable for transportation, the flipping cylinder and the flipping mechanism are controlled to flip the lifting mechanism so that the lifting column is overturned, and the mechanical arm is in a transportation state suitable for transportation; after the mechanical arm is transported to the installation position, the flipping cylinder and the flipping mechanism are controlled to flip the lifting mechanism so that the lifting column is upright, so that the mechanical arm is in a working state, and the slewing mechanism can be controlled to rotate and the lifting mechanism can be raised and lowered as needed, and the telescopic mechanism can be extended and retracted so that the gripper mechanism reaches a position and state suitable for operation. During transportation, the column is overturned by the flipping mechanism, which is more convenient for transportation.
[0131] Based on the same inventive concept, an embodiment of the present invention further provides a pipe laying method, which is implemented using the above-mentioned fully automatic vertical pipe laying device and includes at least one of the following operation processes:
[0132] Discharge process:
[0133] Control the longitudinal travel mechanism on the mechanical arm to drive the slewing mechanism, lifting mechanism, telescopic mechanism and gripper mechanism to move to the wellhead side;
[0134] Control the slewing mechanism to rotate, the lifting mechanism to rise and fall, and the telescopic mechanism to extend and retract, so that the gripper mechanism moves to the gripping position at the wellhead, and controls the gripper mechanism to grip the oil pipe or the pumping rod;
[0135] After the grabbing is completed, the rotary mechanism is controlled to rotate, the lifting mechanism is lifted and lowered, and the telescopic mechanism is telescoped to put the gripper mechanism in a transporting state, and the longitudinal travel mechanism is controlled to drive the rotary mechanism, the lifting mechanism, the telescopic mechanism and the gripper mechanism to move to the side of the pipe rack;
[0136] Control the slewing mechanism to rotate and the telescopic mechanism to extend and retract so that the gripper mechanism moves to the discharge position, and control the lifting mechanism to put the gripper mechanism in a pipe-releasing state, discharge the oil pipe to the oil pipe rack or hang the sucker rod on the sucker rod rack;
[0137] Access process:
[0138] Control the longitudinal travel mechanism on the mechanical arm to drive the slewing mechanism, lifting mechanism, telescopic mechanism and gripper mechanism to move to the side of the pipe rack;
[0139] Control the lifting mechanism to lift and lower, and the telescopic mechanism to extend and retract so that the gripper mechanism moves to the grabbing position of the pipe rack, and control the gripper mechanism to grab the oil pipe from the oil pipe rack or grab the sucker rod from the sucker rod rack;
[0140] After the grabbing is completed, the rotary mechanism is controlled to rotate, the lifting mechanism is lifted and lowered, and the telescopic mechanism is telescoped to put the gripping mechanism in a transporting state, and the longitudinal travel mechanism is controlled to drive the rotary mechanism, the lifting mechanism, the telescopic mechanism and the gripping mechanism to move to the wellhead side;
[0141] The rotary mechanism is controlled to rotate, the lifting mechanism is controlled to rise and fall, and the telescopic mechanism is controlled to extend and retract to move the gripper mechanism to the discharge position, and the gripper mechanism is controlled to be in a pipe releasing state to deliver the oil pipe or the sucker rod to the wellhead.
[0142] In the above discharge process, the implementation of each action of the robot arm's fully automatic pipe discharge operation is described in detail as follows:
[0143] (1) Pipe grabbing: The robot arm is equipped with a gripper mechanism, such as a manipulator. The hydraulic cylinder moves in a telescopic manner to drive the gripper mechanism to open and close the gripper jaws to achieve the pipe grabbing action of the manipulator. Figure 3a-3d Before grabbing the pipe, the manipulator can use the longitudinal travel mechanism to move the gripper mechanism to a position close to the wellhead, and adjust the gripper mechanism to a suitable grabbing position by adjusting the height by the lifting mechanism, adjusting the orientation by the rotating mechanism, and adjusting the extension length of the manipulator by the telescopic mechanism, and then control the gripper mechanism to open the clamp to grab the oil pipe or the sucker rod.
[0144] (2) Transportation management: Transportation management includes a series of actions:
[0145] The mechanical arm lifting column rises to lift the tubing / sucker rod away from the wellhead; the mechanical arm is retracted from the center of the wellhead to the position where it merges with the column, that is, the mechanical arm is in the retracted state, see Figures 4a-4dAs shown, the robot arm rotates to the opening position of the finger beam (i.e., the opening position of the oil pipe limit structure) where the robot finger points, and the robot arm moves on the travel track of the longitudinal travel mechanism to the finger beam groove (oil pipe limit structure) where the oil pipe / sucker rod is placed. The lifting and lowering action of the robot arm lifting column is realized by the extension and retraction of the oil cylinder in the lifting column, the retraction and extension of the robot arm are realized by the extension and retraction of the robot arm extension cylinder, the rotation of the robot arm is realized by the robot arm slewing mechanism, and the movement of the robot arm on the track is realized by the longitudinal travel mechanism.
[0146] After the gripper mechanism grabs the oil pipe or sucker rod, it is raised to a higher height through the lifting column, and the gripper mechanism is retracted to be close to the lifting column through the telescopic mechanism. The gripper mechanism is adjusted to a suitable position for transportation through the slewing mechanism to facilitate transportation of the oil pipe or sucker rod. After being transported to the vicinity of the pipe rack, the lifting column is turned over and made upright.
[0147] (3) Pipe placement: The mechanical arm extends and puts the oil pipe / sucker rod into the finger beam slot set position, which is achieved by the mechanical arm telescopic cylinder. The gripper mechanism can be adjusted to the appropriate pipe placement position by adjusting the height of the lifting mechanism, the azimuth of the slewing mechanism, and the extension length of the mechanical arm through at least one of the following adjustment actions:
[0148] (4) Tube laying: The tubing can be placed at a tubing limit structure of the tubing rack, or the sucker rod can be placed at a sucker rod hanging structure of the sucker rod rack. The mechanical arm column retracts, the tubing is dropped on the bottom plate, or the sucker rod is dropped into the sucker rod finger beam slot, and then the manipulator is released to complete the mechanical arm pipe laying action. The retraction of the mechanical arm column is achieved by the retraction of the cylinder inside the mechanical arm column, and the release of the manipulator is achieved by the mechanical arm opening and closing the tubing extension.
[0149] The above-mentioned process of taking the oil pipe or sucker rod and the above-mentioned discharge process include the reverse actions of the pipe grabbing, pipe transporting, pipe laying and pipe releasing operations.
[0150] In some optional embodiments, the above method further includes at least one of the following processes:
[0151] Device installation process:
[0152] After the transport vehicle transports the pipe racking device to the installation position, the legs of the pipe rack are extended to the first length, and the height of the legs is adjusted to the first height, so that the pipe rack is placed at the installation position under the support of the legs. After the transport vehicle withdraws, the tubing support of the tubing rack on the pipe rack is adjusted to the second height and the sucker rod support on the sucker rod rack is adjusted to the third height;
[0153] Device disassembly process: lower the tubing support of the tubing rack on the tubing rack to the fourth height and lower the sucker rod support on the sucker rod rack to the fifth height, control the transport vehicle to drive to the installation position, retract all the legs of the tubing rack, and let the tubing rack fall onto the transport vehicle.
[0154] When the device is transported, the robotic arm can be overturned using the overturning cylinder, which greatly reduces the transportation size of the robotic arm and improves the transportation stability of the robotic arm.
[0155] The fully automatic vertical pipe laying device provided by the present invention has the characteristics of easy installation, quick debugging, high degree of automation, good operating effect, etc. It can realize the automated and quick operation of grabbing the oil pipe and the sucker rod from the wellhead of the well repair operation, moving from the wellhead to the pipe laying rack, and laying them on the pipe laying rack, thereby improving the operating efficiency of the oil pipe and sucker rod laying, reducing the labor intensity of the operators, and reducing the number of on-site operators.
