Rotation preventing electric dirty shaving device for down-hole oil tube

Abstract

The utility model relates to a down-hole oil pipe rotation preventing type electrical dirty scraping device. A main body is designed into cylindrical-shaped, a fishing head, a centralizer fixed body connected with the fishing head through thread and a rotation preventing arm fixed body connected with the centralizer fixed body through thread are arranged form the upper part to the lower part in sequence, cable holes are arranged at the centers of the fishing head and the centralizer fixed body, a bidirectional cam axle equipped with a cable hole is arranged at the center of the rotation preventing arm fixed body, the upper end of the bidirectional cam axle is connected with the rotation preventing arm fixed body through a screw cap, the lower end is connected with the sheathing thread of a motor through the central hole of the rotation preventing arm fixed body, a cable is connected with the motor through a sealing plug, a sealing sleeve, a pressing screw sleeve, a sliding needle seat and a fixed seat, the pressing screw sleeve is connected with the bidirectional cam shaft through tread, the pressing sealing sleeve and the sliding needle seat are connected with the fixed seat through thread, the fixed seat is connected with the sheathing thread of the motor through thread, the sheathing thread of the motor is connected with a bearing sleeve through thread, the bearing sleeve is connected with a falling prevention screw sleeve through thread, a motor axle is connected with a connecting axle, and the connecting axle is connected with a scraper through thread and a pin. The invention solves the problem that the oil pipe prevents the dirty scraping.

Description

1. Technical field [0001] The invention relates to a scraper for the inner wall of the oil pipe of a water injection well, in particular to an anti-rotation type electric scraper for the downhole oil pipe. 2. Background technology [0002] In the process of oilfield development, due to the long-term sewage injection of water injection wells, a certain section of the inner arm of the tubing is seriously scaled, which makes the downhole testing, salvage, and deployment of instruments unable to pass through, which seriously affects the collection of normal test data of some wells and the layered water injection of water injection wells. and salvage dispenser work. However, some existing commonly used tools cannot meet the needs of the site, so it is an urgent task to solve the problem of oil pipe scraping. 3. Contents of the invention [0003] The purpose of the present invention is to provide an anti-rotation type electric scraping device for downhole tubing, which solves t...
