Abstract

The invention discloses electric control oil well wall salvage equipment which comprises a supporting column. A spiral salvage rod is arranged at the bottom of the supporting column and connected with the bottom end of the supporting column through a rotary shaft, the central lines of the spiral salvage rod, the rotary shaft and the supporting column are located on the same line, and a plurality of barbs are arranged on the spiral salvage rod and made of stainless steel; and the electric control oil well wall salvage equipment further comprises an electromagnetic adsorption plate, the top end of the electromagnetic adsorption plate is connected with the side wall of the supporting column through a connecting arm, a power source device and a driving motor are further arranged at the top of the supporting column, an output shaft of the driving motor is connected with the rotary shaft, and the electromagnetic adsorption plate and the driving motor are connected with the power source device. According to the electric control oil well wall salvage equipment, the problem that in the prior art, attachments of the side wall and the well wall are not prone to being salvaged is solved.

Description

technical field [0001] The invention relates to the petroleum field, in particular to an electronically controlled petroleum well wall fishing equipment. Background technique [0002] In recent years, my country's oil industry has developed rapidly. Due to the promotion of economic interests, oil companies have forgotten the problem of updating and strengthening process technology. In the process of oil field development, many problems have begun to emerge. The fierce competition in oil well development has made The pressure of oil field development has also become extremely huge. In order to keep up with the development of the times, our country has accelerated the progress of development. Then, when developing oil wells, salvaging oil well falling objects has undoubtedly become a difficult problem before us. Most of the bottom-hole fishers in the prior art are designed for the falling objects at the bottom of the well, but there will be a lot of sludge attached to the well...
