摘　　要：沁水盆地是世界上储量较大的高煤阶煤层气田之一,由于该区煤岩储层的研究仍相对薄弱,煤层气的商业性开发至今未取得实质性的突破。重点描述了该区煤岩储层的宏观煤岩类型、显微组分含量、割理发育特征、孔隙结构类型、物性特征、吸附与解吸性能等,分析了对煤层气井产能的主要影响因素。采用模糊物元分析方法,对沁水盆地煤层气高产富集区进行了预测,优选出阳泉-寿阳、长子-屯留、沁水北-安泽和阳城北4个最具潜力的高产有利区,为沁水盆地煤层气后续大规模的开发指明了方向。The Qinshui Basin is one of the biggest high coal rank gasfields with large reserves in the world.The research of coal reservoirs characteristics in Qinshui Basin is very weak,and the commer- cial development of the coal bed methane in Qinshui Basin has not made a breakthrough recently.This paper mainly discusses the macroscopically coal type,microscopic component content, development of cleat and fracture,pore structure type,physical properties,adsorption and desorption ability etc.And the main influencing factors of coalbed methane production are analyzed. High-productivity areas of coalbed methane are predicted accord- ing to the fuzzy matter-element method and four favorable areas, Yangquan-Shouyang,Changzi-Tunliu,Qinshuibei-Anze and Yangchengbei are optimized,which indicate the future large- scale development targets in the coalbed methane of Qinshui Ba- sin.
