Background technology:

[0002] During oilfield production, well repair operations are often required, and during these operations, oil pipes need to be frequently raised and lowered. When raising the oil pipe, after the oil pipe is hung with an elevator, the oil pipe needs to be moved from the wellhead to the oil pipe bridge; when lowering the oil pipe, before the oil pipe is hung with an elevator, the oil pipe needs to be moved from the oil pipe bridge to the wellhead, and the end of the oil pipe needs to be close to the wellhead. When raising and lowering the oil pipe, the oil pipe needs to be lifted and moved horizontally. In the existing technology, manual lifting is often used for oil pipe lifting and moving operations, which is labor-intensive for workers, has low work efficiency, and poses certain safety hazards.

For example, Chinese patent CN201620432431.X discloses a fully automatic oil pipe conveying device, including an automatic oil pipe loading system, an automatic oil pipe unloading system, a guide system, a slideway fixing system, a walking system and a power control system, and a command system; the automatic oil pipe loading system includes an upper pipe sensor, an upper pipe plug, an upper pipe bracket and an upper pipe motor; the upper pipe sensor is arranged at the end of the upper pipe rocker arm; a first driving wheel is installed on the upper pipe motor, and the first driving wheel is engaged with a transmission wheel installed on the upper pipe bracket through a transmission shaft; the upper pipe plug is installed on a slide rail in the middle of the rocker arm, and the upper pipe rocker arm is connected to the transmission shaft; the slideway fixing system is fixed to both ends of the oil pipe slideway by clamping bolts; the command system is fixed to the operating Chinese patent CN201520118464.2 discloses an improved oil pipe conveying device, comprising a base, one end of which is hingedly connected to a first oil cylinder. Two parallel first support beams are symmetrically connected to the top of the first oil cylinder. A pipe groove is provided above the base and connected to the base via second support beams hinged on either side of the base. A rubber sleeve is fixed within the pipe groove. Four arc-shaped protrusions are evenly arranged on the inner side of the rubber sleeve. A rubber guide wheel is movably positioned between two adjacent arc-shaped protrusions. The ends of the rubber guide wheel are fixed to the piston of a fourth oil cylinder. A check device is provided on one side of the rubber sleeve. The check device comprises several annularly arranged rubber friction plates. A first spring body is connected between adjacent rubber friction plates. The outer sides of the rubber friction plates are locked together by an elastic metal hoop. However, these existing technologies suffer from complex structures and low automation levels, making them incapable of lifting and horizontally moving the oil pipe.

[0039] The automatic hydraulic lifting tubing conveyor (hereinafter referred to as the "conveyor") of the present invention is mainly used for automatic lifting and conveying of tubing during well repair operations. The working principle is as follows:

[0040] (1) When lifting the oil pipe and transporting it from the center of the wellhead to the oil pipe bridge:

[0041] Step 1: First, place the conveyor at the designated location, open the fixing pin, extend the auxiliary support rod 2, and adjust the adjustment foot 3 to the appropriate position to make the conveyor equipment stable (refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 );

[0042] Step 2: Start the lifting cylinder of the hydraulic lifting mechanism 6 to perform the lifting action, and the lifting of the hydraulic lifting mechanism 6 drives the top platform frame 7 to lift;

[0043] Step 3: During the lifting process of the top platform frame 7, start the flip hydraulic cylinder 5 of the flip support frame mechanism 8, so that the flip support frame mechanism 8 is flipped up to support the oil pipe lifted out from the operating manipulator in advance (refer to Figure 6 );

[0044] Step 4: When the flip support frame mechanism 8 is about to lower the oil pipe into the roller groove of the third V-shaped roller assembly 71 on the top platform frame 7, the telescopic platform 10 on the top platform frame 7 is extended to the farthest point under the action of the telescopic cylinder 11;

[0045] Step 5: After the oil pipe falls stably into the roller groove of the third V-shaped roller assembly 13, the clamping and flipping mechanism 9 in the open state on the telescopic platform 10 clamps the oil pipe under the action of the clamping and flipping cylinder 92 (refer to Figure 8 )

[0046] Step 6: After the clamping and flipping mechanism 9 clamps the oil pipe, the telescopic cylinder 11 drives the telescopic platform 10 to move away from the drilling center to a set distance, and the oil pipe also moves, thereby driving the oil pipe to move in the horizontal direction (refer to Figure 8 、 Figure 9 ); at the same time, the rotating bridge mechanism 12 is rotated from a vertical state to an inclined state under the action of the rotating cylinder 123; the flip hook mechanism 13 is flipped under the action of the flip cylinder 133, and at the same time, the clamping flip mechanism 9 on the telescopic platform 10 is also rotated by the cylinder, pushing the oil pipe from the roller groove of the V-shaped roller assembly 13 to the rotating bridge mechanism 12, and then the oil pipe rolls down to the oil pipe bridge through the rotating bridge mechanism 12, completing the transportation of the oil pipe from the wellhead center to the oil pipe bridge.

[0047] The rotating bridge mechanisms 12 on both sides can be rotated independently from the vertical position to the inclined position, and can also be rotated from the inclined position to the vertical position, so that the oil pipe can be transported on both sides; the flip hook mechanism 13 can also be flipped on both sides, so that the oil pipe can be flipped on both sides.

[0048] (2) When lowering the oil pipe and transporting it from the oil pipe bridge to the wellhead center:

[0049] The first step is to stabilize the conveyor equipment and the second step is to start the lifting cylinder of the hydraulic lifting mechanism 6 to perform the lifting action. The first and second steps are the same as the above process (1). The rest of the working process is opposite to the above process and is briefly described as follows: During the lifting process of the top platform frame 7, the flip support frame mechanism 8 is first flipped to the third V-shaped roller assembly 71, the rotating bridge mechanism 12 close to the oil pipe bridge side is rotated to the tilted position, the flip hook mechanism 13 and the clamping flip mechanism 9 are flipped to the side of the oil pipe bridge, and when the rotating bridge mechanism 12 in the tilted position reaches an appropriate position lower than the oil pipe on the oil pipe bridge, the operator operates the automated equipment on the oil pipe bridge to push or manually push the oil pipe to roll down to the rotating bridge mechanism 1 2, and then the rotating bridge mechanism 12 rotates, rolling the oil pipe from the rotating bridge mechanism 12 to the V-shaped rod structure of the flip hook mechanism 13, the flip hook mechanism 13 and the clamping and flipping mechanism 9 flip over, pushing the oil pipe to the third V-shaped roller assembly 71 on the top platform frame 7 and the second V-shaped roller assembly 101 on the telescopic platform 10, the clamping and flipping mechanism 9 clamps the oil pipe, and the telescopic platform 10 is extended to the farthest point driven by the telescopic cylinder 11, moving the oil pipe toward the drilling center; then the clamping and flipping mechanism 9 releases the oil pipe, the flip support frame mechanism 8 flips up and lifts the oil pipe at the end of the third V-shaped roller assembly 71 for the operating manipulator to lift the oil pipe, completing the transportation of the oil pipe from the oil pipe bridge to the wellhead center.

[0050] This embodiment utilizes an automated hydraulic lifting tubing conveyor to lift and horizontally move tubing during the frequent raising and lowering of tubing during well repair operations. Automated control of hydraulic or pneumatic cylinders allows for automated, reduced-staff operation, reducing the workload and intensity of well repair workers and improving automation and efficiency.
