Abstract

The invention discloses a salvage auxiliary device, which belongs to the field of oil field exploitation. The device includes: a first connecting sleeve, a motor, a rotating mechanism, a second connecting sleeve, a limit sleeve, a buckle and a first fishing head; the first connecting sleeve is provided with a first cavity, and the motor is located in the first cavity , the power supply end of the motor is connected to the external cable, the power output end of the motor is connected to the rotating mechanism and the limit sleeve in turn, the second end of the first connection sleeve is connected to the first end of the second connection sleeve, and the limit sleeve is located on the second In the inner cavity of the connecting sleeve, the buckle is located in the inner cavity of the limiting sleeve, the first end of the buckle is provided with a locking tooth, the first end of the first fishing head is provided with a first locking slot, and the locking tooth is located in the first locking slot Inside, the second end of the first fishing head is connected with the stuck logging tool. After power is supplied to the motor through the external cable, the locking tooth is disengaged from the first locking slot. The fishing auxiliary device in the present invention provides convenient and fast fishing conditions for the fishing of the stuck logging instrument, and saves time and effort.

Description

technical field [0001] The invention relates to the field of oilfield exploitation, in particular to a fishing auxiliary device. Background technique [0002] During the logging process of an oil well, it is usually necessary to connect the logging instrument to the cable, and then lower the logging instrument to the bottom of the oil well through the cable to obtain data such as the pressure and temperature of the bottom hole fluid, and then pass the obtained data through the cable transmitted to computer equipment on the ground. When it is not necessary to obtain data such as pressure and temperature of the bottom hole fluid, the logging instrument is lifted from the bottom of the oil well through the cable. However, during the process of running the logging instrument into the bottom of the oil well, or during the process of lifting the logging instrument from the bottom of the oil well, the phenomenon that the logging instrument is stuck often occurs, that is, the loggi...
