The invention relates to a salvage tool in a steel wire rope pipe, wherein the salvage tool is used for salvage operation in petroleum and nature gas industries. According to the salvage tool, the problem that at present, barrel-type down-hole drilling tool salvage efficiency is low is solved. According to the technical scheme of the salvage tool, one end of a steel wire rope penetrates through asuspension ring through hole, the steel wire rope is fastened through a steel wire rope clamp to form a rope sleeve, and the other end of the steel wire rope is connected with a ground winch; a servomotor is arranged in a motor cylinder inner cavity, and the upper end of a motor cylinder and the lower end of an end cover are connected in a screw thread mode; an output shaft of the servo motor anda transmission lead screw transmit through transmission keys, and a lead screw sleeve inner cavity is matched with the lower portion of the transmission lead screw to form a lead screw nut pair; theupper end of an upper cylinder body is connected with the lower end of the motor cylinder in a screw thread mode, and the lower end of the upper cylinder body is connected with the upper end of a lower cylinder body in a screw thread mode; and a salvage jaw and a spring are overall arranged in a stepped hole in a centralizer wing of the lower cylinder body, and the upper end of a guiding shoe is connected with the lower end of the lower cylinder body in a screw thread mode. According to the salvage tool in the steel wire rope pipe, through quick lowering of the steel wire rope, the salvage jawis controlled through the servo motor to stretch out to clamp the inner wall of a down-hole drilling tool, quick salvage can be achieved, and the salvage operation efficiency is improved.
Description
technical field [0001] The invention relates to a wire rope inner fishing tool used for fishing in the petroleum and natural gas industry. Background technique [0002] In the oil and gas industry, drilling and completion operations are accompanied by extremely high risks, and accidents occur from time to time. Due to the special environment in the well and the operation of construction personnel, accidents of fish falling to the bottom of the well occur from time to time. Falling fish deposits at the bottom of the well will seriously hinder the progress of drilling and completion operations, causing huge economic losses, and in severe cases, safety liability accidents will occur, so fishing operations must be carried out. The efficiency of fishing operations directly affects the development cost of oil and gas wells, which is of great significance. At present, the routinely used fishing tools include fishing barrels, fishing spears, magnetic fishers and other tools. The lo...
