| 摘 要： | 我国存在不少单一贮层、松软结构、低渗透性的煤层结构,同时这种煤层也多是瓦斯突出区域,对此类结构采用地面压裂技术或水平井技术抽采煤层气,效果十分有限,基于此本文提出一种地面钻井,井下水力对接、水力运移卸压开采煤层气的方法,并对其机理和运行模式进行分析,期望为低渗透性煤层煤层气开采提供一种新思路。

| Abstract: | The structure of coalbed mostly has the characters of single layer,soft structure,and low permeability in China,and it is always the gas outburst area. When extracting coalbed methane,the technology of ground fracturing technology or horizontal well is limited by this structure. Aimed at this problem,this paper proposed a method of surface drilling,underground water butt and water transport relief to extract coalbed methane,analyzed the mechanism and operating mode. It also provided a new idea for the low p... |
