摘　　要：煤层气将成为我国继煤炭和石油天然气之后的战略性接替能源,它的开发和利用既能解决我国天然气的不足,又能从根本上消除了煤炭开采中造成的瓦斯突出等灾害,还可以减少了大量瓦斯排放到大气中造成的环境污染以及改善我国的能源结构。论文详细阐述了煤层气赋存状态、煤层气吸附与解吸机理、煤层气开采基础与提高采收率方法,分析了注气增产法开发煤层气机理,指出了注气增产法开发煤层气的研究方向。Coalbed methane will become a strategically substitute resource of coal, oil and natural gas in China. The development and utilization of coalbed methane can not only make up for the deficiency of natural gas, but also eliminate the disaster of gas outburst during coal mining, moreover, reduce the air pollution from gas emission and optimize the energy structures in China. This paper illustrates occurrences, adsorption, desorption, mining mechanism and recovery of coalbed methane, analyzes the mining mechanism via gas injection to increase coalbed methane recovery and presents a study direction for gas injection to mine coalbed methane.
