Abstract

The invention discloses a liquid oil cavity device for an underground electric control hydraulic drive dual-way power device. The device comprises a high-pressure oil cavity assembly, an oil cavity assembly, an oil cavity joint, a high-pressure oil path, a low-pressure oil path and a cable passage. According to the liquid oil cavity device, underground high-pressure liquid is used for serving as apower source, a piston of the liquid oil cavity device is pushed to move to generate the high-pressure hydraulic oil, the high-pressure hydraulic oil is used for pushing the electric control hydraulic drive dual-way power device to generate mechanical motion, and the device has the beneficial effects of being compact in structure, convenient to use, high in efficiency, capable of precisely controlling the motion displacement amount and the like.

Description

technical field [0001] The invention relates to the field of downhole tools, in particular to a liquid oil chamber device for an electronically controlled hydraulic bidirectional power device in a downhole. Background technique [0002] The national invention patent with the application number 201610123732.9 discloses a downhole electronically controlled hydraulic two-way power device, which uses the annular pressure at the bottom of the well to form a high-pressure loop system and an air low-pressure loop system. The formed high-pressure loop system and the air low-pressure system pass through The opening and closing of the four solenoid valves creates a pressure difference between the upper pressure conversion chamber and the lower pressure conversion chamber, and finally realizes the up and down movement of the oil testing tool and provides two-way power for the downhole tool. However, during the use of this patent, its hydraulic oil reserve is limited, and a special liqu...
