摘　　要：为揭示沁水盆地不同含气区域煤层气产能差异,采用理论分析和数值模拟的方法,研究了沁水盆地典型区块煤层气储层特征及其对产能的影响.基于沁水盆地煤层气井产气量数据,总结发现各区块煤层气产能存在明显差异,分析了影响煤层气井产能的主控因素.提出以目标煤层资源丰度、渗透率、临界解吸压力作为关键参数评价产能方法.研究结果表明:沁水盆地南部煤层气资源可采性优于北部,典型区块煤层气开发前景优劣排序为潘庄、大宁、寿阳、古交.In order to reveal the coalbed methane（CBM） productivity differences of typical blocks in Qinshui Basin, this study utilized the methods of theoretical analysis and numerical simulation to research coalbed methane reservoir characteristics and its effect on productivity of the typical block in Qinshui Basin. Based on CBM well production data, the study identified the productivity differences, and analyzed the main control factors that impact the CBM well productivity. The key parameters including the target coal seam resource abundance, permeability, critical desorption pressure are proposed to evaluate productivity. The results of study show that the southern Qinshui Basin coalbed methane resources are more recoverable than that of the north, a typical block exploitation prospect of CBM in ranking for Pan Zhuang, Darting, Shouyang, Gujiao.
