摘　　要：国内对煤层气的研究已有20年的历程,但至今尚未建立完善的煤层气目标区精选体系,这也制约了我国煤层气大规模工业化开发的步伐。在收集了大量煤层气基础资料和借鉴前人研究成果的基础上,详细分析了煤储层地质因素对煤层气丰度和开发效果的影响,建立了相应的煤层气目标区评价指标体系。通过层次分析法确定权重,利用无量纲化指标处理方法对指标进行标准化处理,采用加权平均模型对目标区进行模糊综合评价。最后以国内部分矿区为例进行了综合评价、排序,实际应用效果良好。Although the study on coalbed methane（CBM） has lasted for 20 years in China,the ranking system of CBM perspectives has not been established,which restricts the large-scale industrial development of CBM.Based on a large number of basic information and former researches on CBM,the influences of geological factors in coal reservoir on the enrichment abundance and the development effect of CBM are analyzed detailedly,and the relevant assessment index system for CBM perspectives is built up.The weight value is determined by AHP and a group of processing functions have been designed for different types of indices.The weighted average model is used to comprehensively evaluate the perspectives.Finally,some CBM regions in China are comprehensively evaluated.The practical application has a good result,so it can be used to effectively guide the exploration and development of the coalbed methane.
