摘要
我国煤矿区地面钻井压裂抽采煤层气(又称瓦斯)技术经过近几年的发展取得长足进展,但地面钻井压裂井下压裂效果考察研究还处于起步阶段。基于地面瓦斯抽采钻井的水力压裂,重点介绍井下压裂效果考察技术和方法,研究考察地面井压裂技术井下压裂区分布范围、裂缝的展布规律,以及压裂对井下瓦斯抽采、采掘生产的影响效果,并形成一套系统的考察手段检验地面压裂井压裂效果,指导地面井压裂抽采煤层气的生产实践。
Coal bed methane （ also known as gas） drainage that through ground drilling fracturing has made considerable progress after years of development in coal mining area, however, the research on underground effect examination of ground drilling fracturing is still in its infancy. Based on hydraulic fracturing of ground gas drainage drilling, effect examination techniques and methods of underground fracturing are introduced emphatically. Distribution of underground fracturing zone and crack distribution law with ground drilling frac- turing techniques and the effects of ground drilling fracturing on underground gas extraction and coal mining and tunneling are re- searched. A system of inspection that tests the fracturing effects of ground fracturing well are formed, which directs production practices of coal bed methane drainage with ground drilling fracturing.
