Novel downhole electronic control power switch

Abstract

The invention relates to the technical field of setting bridge plug devices, in particular to a novel downhole electronic control power switch. The novel downhole electronic control power switch comprises a driving device, a connecting disc, a middle joint, a piston sleeve, a transmission connecting rod, a central rod, a connector and a setting cylinder. The connecting disc, the middle joint, the piston sleeve and the connector are fixedly mounted together in sequence from top to bottom. The outer side of the lower portion of the connector and the inner side of the upper portion of the setting cylinder are connected through a shear pin. The driving device is fixedly mounted on the connecting disc. The structure is reasonable and compact, using is convenient, the driving device, the connecting disc, the middle joint, the piston sleeve, the transmission connecting rod, the central rod, the connector and the setting cylinder are matched with an existing control device, a section hoop positioner and a bridge plug in use, so that the purpose of setting releasing of the bridge plug in a preset position is achieved; the characteristics that safety and reliability are achieved, setting time is short, and taking out to be recycled is facilitated are achieved, operation is convenient, working efficiency is improved, and safe production on site and the quality requirement are met.

Description

technical field [0001] The invention relates to the technical field of setting and sealing bridge plug devices, and is a novel downhole electronically controlled power switch. Background technique [0002] Because the formation sealing technology of cable setting bridge plug has the characteristics of short construction period, accurate positioning of bridge plug sealing position and low construction cost, it is widely used in the formation sealing technology of major domestic oil fields. After the cable bridge plug setting and sealing process, an electrohydraulic bridge plug setting device is widely used now, but the electrohydraulic bridge plug setting device commonly used now has the following problems in use: [0003] 1. The electro-hydraulic bridge plug setting tool is used, and the hydraulic pump starts to work from the ground to the downhole motor until the bridge plug is set and lost. Generally, the required power-on working time is 8 minutes to 15 minutes, and the r...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a new type of downhole electronically controlled power switch, which overcomes the deficiencies of the above-mentioned prior art, and can effectively solve the problem that the existing electro-hydraulic bridge plug setting device has a long time to lose hands, which causes the well entry tool to be easily stuck and unable to be lifted out. Can no longer meet the on-site safety production and quality requirements
