Description

Technical Field

[0001] The utility model relates to the field of oilfield well repair tools, in particular to a pipe lifting rod device. Background Art

[0002] In the well repair operation in the oil field, the pump inspection operation often encounters sand jam, salt jam, wax jam or heavy oil jam in the sucker rod within a certain depth range due to formation sand, high formation water hardness, high wax content in the produced crude oil or too thick oil, which brings great trouble to the well repair construction.

[0003] The current method is to hang the sucker rod reverse device lifting ring with the well workover rig traveling pulley, hang the sucker rod reverse device lifting ring on the sucker rod reverse device lifting card to lift the sucker rod reverse device connected to the sucker rod in the well. After the required reverse load is raised, a cylinder with the same outer diameter of the oil pipe is clamped at the sucker rod body position flush with the main clamp of the tubing hydraulic clamp, and reversed with the tubing hydraulic clamp until the sucker rod above the stuck sucker rod in the well is reversed, the sucker rod lifting card is buckled on the wellhead, the first sucker rod is removed and pulled to the sucker rod bridge, and the wellhead operator removes the sucker rod reverse device at the wellhead, removes the sucker rod reverse device lifting ring and the sucker rod reverse device lifting card, and replaces them with a sucker rod lifting small hook and a sucker rod lifting card. The two sucker rod lifting cards cooperate to lift the reversed sucker rod. When the sucker rod coupling is seen, the first reversed sucker rod is removed and pulled to the sucker rod 1. When the oil pipe is in the well, the oil pump will be turned off and the oil pump will be turned off. After the sucker rod is lifted, the sucker rod hook and the sucker rod elevator are removed, the tubing ring and tubing elevator are replaced, and then the tubing is lifted. The above lifting equipment is repeatedly replaced and the operation process is repeated until the sucker rod and tubing in the well are lifted.

[0004] In the above process, since the specifications of the sucker rod lifting head and the oil pipe lifting head are different, the specifications of the lifting cards and hooks used when lifting the sucker rod and the oil pipe are not universal. Therefore, the sucker rod hook, lifting card and oil pipe lifting ring and lifting card of the traveling pulley need to be replaced frequently, which is time-consuming and labor-intensive and inconvenient for the personnel on duty to operate.

[0020] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0021] In the prior art, when the sucker rod is stuck and the oil pipe is lifted, the sucker rod is lifted to a certain load and turned upside down, and the sucker rod is lifted out with a small hook and a lifting card, and then the oil pipe lifting ring and the lifting card are replaced to lift the oil pipe. When the sucker rod is stuck, the sucker rod is turned upside down and then the sucker rod is lifted out with a small hook and a lifting card, and then the oil pipe lifting ring and the lifting card are replaced to lift the oil pipe. This cycle is repeated until the oil pipe and the sucker rod in the well are lifted. This process is time-consuming and labor-intensive, and is not convenient for personnel to operate. In view of the above problems, the utility model designs a pipe lifting rod device. The core concept of the utility model is to set an oil pipe short circuit that is compatible with the oil pipe lifting lifting card at the upper end of the sucker rod short circuit, so that the same lifting card and lifting ring can be used when lifting the sucker rod and the oil pipe, thereby avoiding repeated replacement of lifting equipment.

[0022] Based on the above invention concept, Figure 1 and Figure 2 As shown, a pipe lifting rod device of the utility model comprises a sucker rod short circuit 2 connected to a sucker rod 4 in a wellhead pipe column, and an oil pipe short circuit 1 adapted to an oil pipe lifting elevator 3 is fixedly connected to the upper end of the sucker rod short circuit 2.

[0023] Among the above components, Figure 1 and Figure 2 In the embodiment shown, the tubing short-circuit 1 is a hollow cylinder, which is compatible with the shape and specification of the tubing lifting elevator. The lower end of the tubing short-circuit 1 is provided with an internal thread, which is threadedly connected with the sucker rod short-circuit 2. The tubing short-circuit 1 and the sucker rod short-circuit 2 are stepped as a whole, and the outer diameters decrease from top to bottom, which can prevent the tubing lifting elevator 3 from moving up and away from the tubing short-circuit 1 when lifting the sucker rod 4.

[0024] In such Figure 1 and Figure 2In the embodiment shown, the sucker rod short-circuit 2 is in the shape of a hollow cylinder, which is compatible with the shape and specification of the sucker rod 4. The sucker rod short-circuit 2 is provided with an upper joint 201 and a lower joint 202. The upper joint 201 is provided with an external thread, which is threadedly connected to the lower end of the tubing short-circuit 1. The lower joint 202 is also provided with an external thread, which is threadedly connected to the coupling of the sucker rod 4, and can be easily disassembled. The buckle type of the external thread on the upper joint 201 is opposite to the buckle type of the external thread on the lower joint 202. In the process of rotating the sucker rod short-circuit 2 to drive the downhole sucker rod 4 to rotate and release, it can be ensured that the connection between the tubing short-circuit 1 and the sucker rod short-circuit 2, and the connection between the sucker rod short-circuit 2 and the sucker rod 4 will not be released, and safe operation can be achieved.

[0025] In such Figure 1 and Figure 2 In the illustrated embodiment, the diameter of the tubing short-circuit 1 is larger than the diameter of the sucker rod short-circuit 2, and the tubing short-circuit 1 and the sucker rod short-circuit 2 are centrally connected, which can ensure that the entire device is subjected to balanced force during operation and operates more smoothly.

[0026] In some other embodiments, the sucker rod short-circuit 2 and the oil pipe short-circuit 1 may also be solid cylinders, and the connection method thereof may also be welding connection, or they may also be integrally processed and formed.

[0027] When the pump is stuck during the well repair operation, the pipe lifting device uses the tubing lifting card 3 to clamp the tubing short-circuit 1, and then the tubing lifting ring 7 is hung on the traveling block big hook 6 of the traveling block of the well repair rig, and the well repair rig is used to lift it to the top of the wellhead, and then it is lowered to connect the lower joint 202 of the sucker rod short-circuit 2 with the sucker rod 4 coupling in the well, and the tubing short-circuit 1 is lifted to the required load and reversed with the hydraulic lifting clamp, and the tubing short-circuit 1 and the sucker rod short-circuit 2 are rotated counterclockwise with the hydraulic lifting clamp, and the upper joint 201 of the sucker rod short-circuit 2 will not be loosened due to the forward rotation buckle type, until the sucker rod 4 stuck at the lower part is reversed, and the reversed part of the sucker rod 4 is lifted up by the pipe lifting device When the sucker rod 4 coupling is seen, the first sucker rod 4 that has been inverted is removed and pulled onto the sucker rod 4 bridge, and all the inverted sucker rods are continued to be pulled out one by one, and then the pipe lifting rod device is removed, and the tubing hanging elevator 8 is connected to the tubing lifting ring 7 to lift the tubing 5. When the tubing 5 coupling is seen, the first tubing 5 is removed, and the tubing 5 is continued to be pulled out one by one until the stuck sucker rod 4 is encountered, and then the tubing lifting elevator 3 is used to install the pipe lifting rod device to repeatedly lift, invert, and lift the sucker rod 4 and the tubing 5, until the tubing 5 and the sucker rod 4 in the well are lifted and completed, thereby avoiding the problem of replacing the sucker rod hook and the elevator, the tubing lifting ring and the elevator back and forth, reducing labor intensity and improving work efficiency.
