Description

Technical Field

[0001] The utility model belongs to the technical field of oil field salvage, and in particular relates to a novel salvage device. Background Art

[0002] Side Opening Non-Electric Cable Retrieve is a tool used to retrieve instruments dropped into oil wells. Side Opening Non-Electric Cable Retrieve is usually used in oil and gas well logging operations.

[0003] In recent years, the tools used in well logging and salvage operations are all cava salvage tubes and three-ball salvage devices. When salvaging instruments, existing core-penetrating salvage tools need to cut off the cable before construction operations can be carried out. During the salvage operation, since the status of the downhole instruments is not understood, the cable will be greatly damaged during the salvage.

[0004] The existing Chinese utility model patent 200620158756.X has three equally divided oblique through holes on the body wall, a steel ball at the bottom of the oblique through hole, a compression spring on the upper part of the steel ball, and a wire plug on the upper part of the spring to seal the oblique hole, so that construction and salvage can be carried out without cutting the cable. However, during salvage, the salvage device needs to be continuously rotated to allow the instrument dropped in the well to enter the salvage device body, which is very cumbersome to operate and has low salvage efficiency. In order to keep a good holding force on the salvage device body, the spring needs to be continuously replaced in batches, which not only increases the cost of later maintenance and repair, but also seriously affects the work efficiency of salvage.

[0005] In summary, a new salvaging device is urgently needed to solve the problem that the existing salvage device frequently replaces batches of springs, which not only reduces work efficiency but also causes great waste. Utility Model Content

[0006] The embodiment of the utility model provides a novel salvage device, aiming to solve the problem that the existing salvage device has to frequently replace batches of springs, which not only reduces the working efficiency but also causes great waste.

[0007] The utility model embodiment is achieved in this way:

[0008] A new type of salvage device, comprising:

[0009] A locking body, a detachable connecting body is provided at the front end of the locking body, a detachable guide shoe body is provided at the rear end of the locking body, a connecting through groove is provided at the front end of the connecting body, and the roller is installed in the connecting through groove through a roller pin;

[0010] A connecting hole is provided in the locking body, a locking spring and a steel ball are installed in the connecting hole, the locking spring and the steel ball are fixed to the locking body through an adjusting screw plug, an internal thread is provided in the connecting hole, and the adjusting screw plug can be fixed in the connecting hole through the thread;

[0011] The guide shoe main body is provided with a guide shoe movable block, the locking body is provided with a locking body movable block, the connecting body is provided with a connecting body movable block, and the connecting body on one side of the roller is provided with a main body locking screw.

[0012] Furthermore, a connector block is embedded in the middle of the connecting body, the connecting body at the front end of the connecting body block is connected to the connecting groove, and a connecting hole is provided at the front end of the connecting body, and the connecting hole can be connected to the drilling tool through a thread.

[0013] Furthermore, the locking body is provided with a plurality of connecting holes, which are evenly distributed in the locking body along the circumferential direction of the locking body, and internal threads are provided in the connecting holes.

[0014] Furthermore, the front end of the locking body is provided with an external thread, and the rear end of the locking body is provided with an internal thread.

[0015] Furthermore, the front end of the guide shoe body is provided with an external thread, the rear end is provided with an open guide hole, the middle part of the guide shoe body is provided with a guide shoe through groove, and the guide shoe movable block is provided in the guide shoe through groove.

[0016] Furthermore, a detachable locking body movable block is connected in the middle of the locking body.

[0017] A side-opening continuous cable salvage device comprises the above-mentioned adjusting screw plug.

[0018] The beneficial effects achieved by the utility model are:

[0019] The utility model has an internal thread in the connecting hole, and the adjusting screw plug can adjust the pressure of the locking spring through the thread, thereby changing the pressure of the steel ball in the connecting hole. When it is necessary to increase the pressure of the locking spring on the steel ball, the adjusting screw plug is screwed forward into the connecting hole, and when it is necessary to reduce the pressure of the locking spring on the steel ball, the adjusting screw plug is screwed out of the connecting hole in the opposite direction, thereby adjusting the pressure of each spring respectively, thereby achieving that the pressure of each steel ball is equal and the clamping force generated is the same. Compared with the existing salvage device, the utility model can make each spring generate equal pressure through the adjusting screw plug, so that the salvage device generates a stable clamping force, saves cost investment, shortens the number of times of replacing the spring, and thereby increases the efficiency of salvage.
