Description

Technical Field

[0001] The utility model relates to the technical field of salvage devices, in particular to a rapid salvage device in the production process of an oil and gas well. Background Art

[0002] Oilfield wells are wells specially drilled for the extraction of oil and natural gas. They are holes drilled in underground strata according to a certain well layout system and are used to extract underground oil or natural gas. During the extraction and logging operations of oil and gas wells, conventional salvage tools can salvage rope-shaped well fallen objects in the pipe, such as steel wire, hemp rope, etc. If small and irregular objects such as cloth pieces, oil-absorbing felt, etc. fall into the pipe, it will be difficult to perform the salvage operation.

[0003] In the Chinese utility model patent application number: CN201420295248.0, there is disclosed a fishing claw for fine debris in the pipe of oil and gas wells. The fishing claw is evenly distributed on the inner surface of the fishing tube through welding, and is quickly lowered to the position of the fallen object and inserted into the fallen object in the well. At the same time, the fishing claw pierces the fallen object and can be lifted up to salvage the fallen object. If the size does not meet the requirements of the operation, the operation site can be processed and designed according to the situation, which is convenient and simple, and has strong operability.

[0004] Although the above patent realizes the function of assisting the salvage of fallen objects in oilfield wells, the above patent has the following disadvantages when used: the above oil and gas well pipe fine debris salvage claw lacks a protective mechanism for the claw when in use, and the claw is exposed to the outside when not in use, which is easy to be damaged, affecting the service life of the device and inconvenient to use. Therefore, we propose a rapid salvage device in the production process of oil and gas wells. Utility Model Content

[0008] Preferably, the outer side of the fixing rod is fixedly connected with a second retaining ring and a first retaining ring in sequence from top to bottom. The arrangement of the first retaining ring and the second retaining ring can limit the movement stroke of the protective tube, making it convenient for the connecting block to enter the interior of the slot to fix the position of the protective tube.

[0009] Preferably, the interior of the protective tube is symmetrically slidably connected to a sliding rod, the slider is fixedly connected to the sliding rod, and a spring is sleeved on the outside of the sliding rod and on one side of the slider. The slider is moved by the sliding rod, and is moved and reset by the spring, thereby assisting in fixing the position of the protective tube.

[0010] Preferably, the outer side of the fixing rod is fixedly connected to a fixing frame, the interior of the fixing frame is slidably connected to an adjusting block, one side of the adjusting block is fixedly connected to a locking block, the locking block is slidably connected to the fixing rod, the top of the insertion rod is fixedly connected to a mounting block, the interior of the mounting block is provided with a fixing groove used in conjunction with the locking block, the locking block is moved by the movement of the adjusting block, so that the locking block moves into the interior of the fixing groove, thereby locking the position of the mounting block, making it convenient for disassembly and assembly of the insertion rod.

[0011] Preferably, a threaded rod is rotatably connected inside the fixed frame, the adjustment block is threadedly connected to the threaded rod, and a handle is fixedly connected to one end of the threaded rod. The handle drives the threaded rod to rotate, and the rotation of the threaded rod drives the adjustment block to move, thereby assisting the disassembly and assembly of the insertion rod.

[0012] Preferably, a fixing ring is fixedly connected to the outer side of the fixing frame, and a protective cover is threadedly connected to the outer side of the fixing ring. The setting of the fixing ring and the protective cover can protect the handle to prevent accidental contact. When the handle needs to be operated, just unscrew the protective cover.
