Electric Packer

Abstract

The invention relates to the technical field of underground packing devices, and provides an electric packer which comprises an oil pocket, an upper oil storage chamber joint, a lower oil storage chamber joint, a motor mounting base, a pump mounting base, a non-return valve device, a central pipe, a rubber tube assembly, a valve rod seat, an un-setting valve rod and an un-setting assembly, wherein the upper part of the oil pocket and the lower part of the upper oil storage chamber joint are fixedly mounted together; the lower part of the oil pocket and the upper part of the lower oil storage chamber joint are fixedly mounted together; the lower part of the lower oil storage chamber joint and the upper part of the motor mounting base are fixedly mounted together. The electric packer has the advantages that the structure is simple and compact; the use is convenient and reliable; electro-hydraulic energy sources are adopted as power; due to circuit control, setting and un-setting can be realized electrically; the isolation cleanliness is high; the blockage possibility of a setting passage is low; long-term sealing can be realized; controllability of setting and un-setting is high; no bulky complex setting equipment is required for a wellhead; the work efficiency is improved effectively; the equipment mounting cost is reduced.

Description

technical field [0001] The invention relates to the technical field of downhole packing devices, and is an electric packer. Background technique [0002] At present, the expansion packer commonly used in oilfields is set by pressing the wellhead into the pipe string and using well fluid to set, and the unsealing is realized by means of pressure relief or reverse pressure. For testing, the packer is required to have the conditions of long operating time, long sealing time, easy seating and unpacking, and the commonly used expanding packer cannot meet the oil testing operation of the horizontal well section. SUMMARY OF THE INVENTION [0003] The present invention provides an electric packer, which overcomes the above-mentioned deficiencies of the prior art, and can effectively solve the problem that the commonly used expansion packer cannot meet the operating conditions for oil testing and testing of horizontal well sections. [0004] The technical scheme of the present inv...
