Description

technical field [0001] The invention relates to the field of an oil field downhole sealing system, in particular to an electrohydraulic bridge plug sealing system. Background technique [0002] Due to the non-uniformity between the oil layers in which the oil is stored, and the different physical and chemical properties of the crude oil, it is necessary to take measures for layered oil recovery in the process of oil recovery in order to maximize the ultimate recovery. To achieve oil recovery in layers, an appropriate sealing system must be used. [0003] The bridge plug is a downhole sealing system for oilfields. It has a reliable two-way pressure bearing function and can be used for temporary, permanent and selective sealing of oil and gas layers. It has a wide range of applications in oil and gas field development. The currently used bridge plugs mainly include coiled tubing-transmitted water pressure seat seals and cable-transmitted explosive seat seals. The former needs...
