摘要： 采用灰色关联分析方法确定了评价指标的权重，利用多级和梯形隶属度函数确定了指标的单因素评价，建立了煤层气资源地面开发选区模糊综合评价模型.利用Matlab编制了CBMES(coalbedmethaneevaluationsystem)，对辽宁省7个主要煤田煤层气地面开发可行性进行了模糊综合评价.根据评价结果，各评价指标中煤层渗透率和含气量所占权重较大，其他指标权重由大到小依次为:煤层厚度、煤级、资源量、资源丰度、煤层压力、埋深.辽宁省各煤田煤层气开发可行性为:阜新煤田>铁法煤田>抚顺煤田>红阳煤田>沈北煤田>康平煤田>南票煤田，评价结果与实际开发情况吻合较好，证明了所建立模糊综合评价模型的合理性.

Abstract: The weights of evaluation indexes were confirmed by grey correlation analysis. Singlefactor fuzzy evaluation was determined by multistage and trapezoid membership function. Fuzzy comprehensive evaluation model for the feasibility study of CBM development was established. Based on the fuzzy comprehensive evaluation model CBMES (coal bed methane evaluation system) was developed by using Matlab， and it was employed to evaluate the CBM development feasibilities of seven main coalfields in Liaoning Province. According to the evaluation results， the weights of coal permeability and methane content are higher. Other indices， such as thickness of coal bed， coal rank， resource capacity， resources abundance， coal bed pressure， and burial depth are ranked in descending weight order. The feasibility of CBM development ranked in descending order is:Fuxin coal field， Tiefa coal field， Fushun coal field， Hongyang coal field， Shenbei coal field， Kangping coal field， and Nanpiao coal field. The results are in agreement with the in situ condition， which shows the rationality of fuzzy comprehensive evaluation model for the CBM development feasibility.

Key words: CBM(coal bed methane), ground development, area selection, grey analysis, fuzzy comprehensive evaluation
