Coal bed methane(CBM) is a kind of unconventional natural gas,its"classifies"characteristics are different from the life of the conventional gas,reservoir,cap,luck,get together,the basic accumulation geological conditions,enrichment of the basic conditions of the coal bed methane mainly includes the generation condition, reservoir condition and preservation conditions. Through analyzing a large amount of literature research at home and abroad,the coal seam thickness,coal metamorphic grade,coal and rock composition,pore-coal and rock fracture structure and sealing condition, hydrogeological condition, seven factors such as tectonic conditions of coal bed methane rich integration control function. To coal bed methane accumulation in the field of new progress were sum-marized,points out the development direction in the future.%煤层气是一种非常规天然气,其"自生自储"的特点与常规天然气的生、储、盖、运、聚、保等基本成藏地质条件不同,煤层气成藏富集的基本条件主要包括生成条件、储集条件和保存条件.通过对国内外大量文献的调研,分析了煤层厚度、煤变质程度、煤岩组分、煤岩孔隙-裂隙结构、封盖条件、水文地质条件、构造条件等7个因素对煤层气富集成藏的控制作用.对煤层气聚集成藏领域的新进展进行了综述,并指出了其未来的发展方向.
