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。
Through the study on the evolution of coal seam’s raw, reservoir, cover, tectonic evolution and hydrogeology, the prospect of CBM development in the study area is discussed. The results show that: the main coal seams in the area have good potential for gas generation, reservoir capping and cap capping; tectonic evolution and hydrogeological conditions are the main factors that affect CBM enrichment; CBM reservoirs are mainly characterized by small and medium scale structures The trapped gas reservoirs exist in the form of large-scale hydrodynamic gust or complex trap gas reservoirs in the deep area. The deep buried depth of 600-1,500 m in the southwestern Liulin coal seam is the preferred area for further development.
