Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-efficiency filter type shale gas extraction device, which solves the problem of shale gas often being mixed with high-speed moving impurities when shale gas is extracted and collected. When the shale gas is collected, the stones in the shale gas cannot be intercepted, so that the internal structure is damaged due to the collision of high-speed impurities

Abstract

The invention discloses an efficient filtering type shale gas mining device which comprises a mining shell, an outer anti-extrusion plate is fixedly connected to the top of the mining shell, a collecting pipe shell is fixedly connected to the upper surface of the outer anti-extrusion plate, an inner expansion plate is fixedly connected to the inner wall of the collecting pipe shell, and a collecting device is fixedly connected to the interior of the mining shell. The collecting device comprises an upper sealing collecting pipe, the outer surface of the upper sealing collecting pipe is arranged in the exploiting shell in a sleeved mode, and an exploiting unit is fixedly connected to the bottom of the inner surface of the exploiting shell. According to the efficient filtering type shale gas exploitation device, by arranging the top sleeve cover, when the device is impacted by high-pressure shale gas at the bottom, the action spring can achieve a proper blocking effect by limiting the bottom of the force bearing elastic rod, and the situation that the impact force of the flow velocity of the shale gas is too large, and consequently the internal device structure is damaged is prevented.

Description

technical field [0001] The invention relates to the technical field of shale gas exploitation equipment, in particular to a high-efficiency filter type shale gas exploitation device. Background technique [0002] Shale gas is natural gas extracted from shale layers, mainly composed of methane, and is an important unconventional natural gas resource. The formation and enrichment of shale gas has its own unique characteristics, and it is often distributed in the thick and widely distributed shale source rock formations in the basin. Compared with conventional natural gas, shale gas reservoirs have the characteristics of self-generation and self-storage. Shale is both a source rock and a reservoir, which is not controlled by structure, has no traps, and has no clear gas-water interface. Shale gas has a wide range of burial depths, ranging from 200 meters to more than 3,000 meters. Most gas-producing shale is widely distributed, thick, and generally contains gas, which enables...
