Example Embodiment

[0021] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, according to the preferred embodiment of the present invention, the coal-bed methane capture tube includes a tube body 1 and a multi-angle continuous keyway hole 2 formed on the tube body 1. The tube body 1 has an outer wall 1a and an inner wall 1b. The thickness between 8-12mm. Each through hole 2 has an outer wall 1a and an inner wall 1b of the tube body 1. The pipe body 1 is preferably made of HDPE material to ensure the stability of the coalbed methane collection pipe and prevent it from being damaged by underground moisture and chemical environments.

[0023] Such as figure 1 As shown, the through holes 2 are preferably aligned and evenly distributed in the longitudinal direction of the tube body 1, and the through holes 2 are through holes and are formed in a straight...

Abstract

The invention provides a coal bed gas collecting pipe and a processing method thereof. The coal bed gas collecting pipe comprises a pipe body and continuous gas suction key slot type row holes which are uniformly distributed on the pipe body at multiple angles, wherein the pipe body is provided with an inner wall and an outer wall; each key slot type through hole is connected with the inner wall and the outer wall of the pipe body; and the through holes are linearly distributed uniformly along the longitudinal direction of the pipe body, and are distributed in a staggered way along the circumferential direction of the pipe body. The coal bed gas collecting pipe provided by the invention is penetrated into a coal bed for collecting coal bed gas in a coal bed gas well, so that the exploitation and utilization efficiencies of coal bed gas can be increased effectively, and the yield of coal bed gas is increased; and moreover, the processing method of the coal bed gas collecting pipe is low in cost, is implemented through a simple process, and has a high automatic degree.

Description

technical field [0001] The invention relates to the field of coalbed methane exploitation, in particular to a coalbed methane collecting pipe and a processing method thereof. Background technique [0002] Coalbed methane (commonly known as gas) is a self-generated and self-storage unconventional natural gas, which is an associated gas of coal. As a new type of clean energy, it has become one of the best energy and chemical raw materials in the 21st century. At the same time, coalbed methane is also the root cause of explosion accidents in the process of coal mining. The mining of coalbed methane is of great significance to alleviate the contradiction between supply and demand of energy, ensure the safety of coal mining, improve the efficiency and output of comprehensive coal mining, and implement the energy strategy of sustainable development. [0003] Coalbed methane mainly exists in the coal seam in the state of adsorption, and it is very difficult to mine. There are thre...
