Bridge plug test device and cleaning method

Abstract

The invention discloses a bridge plug test device cleaning method and belongs to the technical field of oil field oil recovery equipment. A test device comprises a magnalium bridge plug body, a magnalium connecting disc, a magnalium connecting column and a magnalium bridge plug joint. A blind hole is vertically opened in the bottom of the magnalium bridge plug body, a through hole is formed in thetop of the inner cavity of the blind hole, the magnalium connecting disc is inserted into the inner cavity of the blind hole, and a hexagonal through hole is vertically formed in the central positionof the magnalium connecting disc body. The bridge plug test device cleaning method specifically includes the following steps of a) disassembly; b) cleaning; c) drying; d) plating. According to the method, an operator can remove and repair a bridge plug conveniently and clean the bridge plug conveniently, scratch caused by friction between the bridge plug and the well wall is effectively avoided,and the normal use is not affected.

Description

technical field [0001] The invention relates to the technical field of oil production equipment in oil fields, in particular to a bridge plug test device and a cleaning method. Background technique [0002] Bridge plug is a kind of equipment used for sealing layers in oil and gas wells. It has the characteristics of less construction procedures, short cycle time, and accurate sealing position. Therefore, bridge plugs have been widely used in the fields of oil production and maintenance of oil and gas wells. , Chinese patent application number CN201720090538.5, proposes a bridge plug with a bridge plug test device assembly, including a bridge plug body with a large diameter central hole inside the bridge plug body; a bridge plug joint connected to the bridge plug body, and The bridge plug joint has a joint center hole inside, and the inner diameter of the joint center hole is smaller than the inner diameter of the large diameter center hole; the stopper assembly, the stopper ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a bridge plug test device and cleaning method to solve the problem in the above background technology that the bridge plug assembly of the bridge plug is arranged in the inner cavity of the large diameter central hole, and no corresponding auxiliary disassembly is provided. The structure makes it inconvenient to disassemble the bridge plug assembly. There is no certain sealing structure at the connection between the bridge plug joint and the bridge plug body. It is easy for the liquid to leak during the seat seal, which affects the normal operation of the bridge plug. A certain protective structure, when extended into the well, is prone to friction on the well wall, causing scratches on the bridge plug body, which affects the use of the problem
