Abstract

The invention discloses a novel hydraulic back-off device comprising an anchoring device, a pressurizing device, a power transmission device and a power output device. The pressurizing device used for increasing the pressure is arranged on the lower portion of the anchoring device. The power transmission device used for power transmission is arranged on the lower portion of the pressurizing device. The power output device for outputting the hydraulic pressure is arranged on the lower portion of the power transmission device. Compared with the prior art, hydraulic drive is adopted as driving force; an axial power shaft, a quick-replacement drive head and a rotating power shaft are taken as a main power actuator; the axial power shaft and the quick-replacement drive head are of a split type structure so that parts can be machined, replaced and maintained easily; a double ratchet set is designed for power output, an inner ratchet and an outer ratchet are mutually independent, the inner ratchet is not affected by the lower rotary torque, and the outer ratchet guarantees that rotating of the back-off torque is avoided, so that reliable and safe operation of the tool is guaranteed, the output torque is large, and operation is easy.

Description

technical field [0001] The invention relates to the field of oil exploitation equipment, in particular to a hydraulic undercut tool for highly deviated wells and horizontal wells. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous attenuation of oil and gas field development and non-renewable resources, in order to alleviate the situation that my country's oil and gas resources are overly dependent on imports, major domestic oil fields have accelerated the exploration and development of oil and gas resources. The development process of oil and gas wells In the middle, especially in the late stage of oil well production, it is necessary to implement production stimulation measures. During the process of drilling workover / production stimulation measures, pipe string jamming accidents often occur. Once a stuck accident occurs, it will be very troublesome to deal with, which will increase the operation cycle and co...
