Electronic control hydraulic automatic setting bridge plug device

Abstract

The invention provides an electronic control hydraulic automatic setting bridge plug device. The electronic control hydraulic automatic setting bridge plug device comprises a control device, a collar locator, a bridge plug hydraulic setting device and a bridge plug, wherein the collar locator, the bridge plug hydraulic setting device and the bridge plug are sequentially fixed and mounted together from top to bottom; the bridge plug hydraulic setting device comprises a driving device, an intermediate joint, a piston sleeve, a connector and a setting drum; and a signal input terminal of the control device and a signal output terminal of the collar locator are electrically connected together by virtue of an electric cable, and the signal input terminal of the control device and a signal input terminal of the driving device of the bridge plug hydraulic setting device are electrically connected together by virtue of an electric cable. The electronic control hydraulic automatic setting bridge plug device is reasonable and compact in structure and easy to use; by virtue of coordinated application of the control device, the collar locator, the bridge plug hydraulic setting device and the bridge plug, the aims of setting and releasing at a preset position by the bridge plug are realized; the electronic control hydraulic automatic setting bridge plug device has the characteristics of safety, reliability, short setting time and convenience in taking out and recycling of the bridge plug; and the operation is facilitated, the working efficiency is improved, and on-site safety production and quality requirements are met.

Description

technical field [0001] The invention relates to the technical field of setting and sealing bridge plug devices, and relates to an electronically controlled hydraulic automatic setting and sealing bridge plug device. 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 ti...
