Oil well downhole rope fishing device

Abstract

The invention discloses an oil well downhole rope fishing device, and relates to the field of oil exploitation equipment. A plurality of hanging rings are arranged on one end face of a supporting base of the oil well downhole rope fishing device, an air bag with a cavity is fixedly arranged on the other end face of the supporting base, a plurality of fishing conical barbs are densely distributed on the surface of the air bag, and an inflation pipe penetrates through the supporting base to be communicated with a cavity of the air bag. When the fishing device is in use, the air bag can be kept in the deflated state, the hanging rings are hung through hanging ropes, the oil well downhole rope fishing device is placed to the bottom of a petroleum well, the end of an inflation pipe is reserved outside the oil well opening, an inflation device is used for inflating the cavity of the air bag through the inflation pipe, the air bag is plumped up gradually, the fishing conical barbs are erected, the inner wall of the whole oil well is filled with the fishing conical barbs, a rope-shaped tool can be stabbed by the fishing conical barbs conveniently, and rope-shaped parts can be efficiently fished out.

Description

technical field [0001] The invention relates to the field of oil exploitation equipment, in particular to an oil well downhole rope fishing device. Background technique [0002] During the exploitation of oil wells, rope-like tools often fall into them. If they are not salvaged in time, the oil wells will be in danger, resulting in blockage of the oil wells and affecting the production of the oil wells. The design of the existing rope tool fishing equipment for oil wells is too simple. When fishing, only rely on the hook-shaped parts to hook the rope and pull the wound. The operation is difficult and the fishing efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil well downhole rope fishing device. By setting the salvage cone thorn outside the airbag, the airbag is put into the bottom of the oil well and then inflated, so that the salvage cone thorn sticks to the rope-shaped parts, so that th...
