Problems solved by technology

[0003] At present, when the downhole drilling tool is stuck in the oil field, the lifting capacity is insufficient. Especially when the drill pipe is used to salvage and release the sticking, the lifting capacity of the minor repair equipment is even more serious. At this time, only the replacement of the overhaul equipment should be considered. The team, on the one hand, also wastes manpower, material resources and costs, so now there is an urgent need for a workover and salvage power-increasing auxiliary device

Abstract

The invention discloses an auxiliary device for workover salvage enhancement. The auxiliary device for workover and salvage enhancementcomprises a lifting part,when a user wants to use the auxiliary device forworkover salvage enhancement, a crane is connected with a lifting hole on the lifting part, the lower end of a piston rod is connected witha pipe column in a well,the upper and lower oil inlet joints are connected with external oil inlet pipes respectively,the oil inlet pipe is connected witha hydraulic pump,a bolt connection hole on a lower cylinder head is in bolt connection withan upper flange of ablowout preventer,the auxiliary device for workover and salvage enhancement is fixed toa wellhead, high-pressure oil enters into a lower oil cavity inside the lower end of the cylinder body through the lower oil inlet in the lower joint,the high-pressure oil pushes a piston upward, the piston drives the piston rod upward, the high-pressure oil enters intoanupper oil cavity inside theupper end of the cylinder body through the upper oil inlet in the upper joint until reset, the piston and piston rod are pushed downward to realize the reset,and by arranging a first connection piece,a second connection piece, a third connection piece, a fourth connection piece, and a fifth connection piece, tightness of the entire device is ensured.

Description

technical field [0001] The invention relates to an oil field mechanical equipment, in particular to a workover and fishing booster auxiliary device. Background technique [0002] Petroleum is an indispensable source of energy in life. People's demand for petroleum is increasing day by day, so there are more and more petroleum exploration industries. At present, in drilling and workover operations, due to the performance of drilling fluid, geological conditions and long-term Due to reasons such as high-intensity mining, the rock cementation strength is reduced or destroyed, and the formation is sanded or collapsed, resulting in downhole stuck pipe. [0003] At present, when the downhole drilling tool is stuck in the oil field, the lifting capacity is insufficient. Especially when the drill pipe is used to salvage and release the sticking, the lifting capacity of the minor repair equipment is even more serious. At this time, only the replacement of the overhaul equipment shoul...
