【摘要】 通过对煤层生、储、盖、构造演化史及水文地质特征的研究，讨论了研究区煤层气开发的前景。结果表明：区内主要煤层具有良好的生气潜能、储集和盖层封盖性能；构造演化和水文地质条件是影响煤层气富集的主要因素；煤层气藏在浅部区主要以中小规模构造圈闭气藏的形式存在，深部区为较大规模的水动力圈团或复合圈闭气藏；柳林西南煤层６００～１５００ｍ埋深区域是目前进行进一步开发工作的首选区域。更多还原

【Abstract】 Basing on the study of the generation,reservoir,cap,tectonic evolution history and hydrological characters,the authors discuss the coalbed gas exploitation future of the research region The conclusions are:the main coal seams have good generation potential,and the reservoir and cap characters;the tectonic evolution and hydrological condition are the main control factors of the coalbed gas’s concentration;the coalbed gas pools in shallow area are mainly of small to middle scaled structure trap gas pools,while in deep area they are mainly of larger scaled hydrodynamic and combination trap pools’ it is infered that the coal seam buried between 600 1500 m in the southwest of Liulin is the best region for further exploitation更多还原
