摘　　要：借鉴以往煤层气资源评价成果,以全国121个含气区带为评价单元,主要考虑地质条件、资源量、开发程度等因素,排序采用多层次筛选,筛选出41个煤层气有利区。运用聚类分析法对筛选出的41个有利区进行了分类。通过对比各分类区块煤层气资源优劣,优选出沁水、鄂东、鄂南、准南、准东、依兰、珲春、铁法、阜新、宁武、西山、焦作、淮北、松藻、丰城15个煤层气勘查开采有利区,总面积5.07万km2,埋深1 000m以浅的煤层气地质资源量4.47×1012m3。Benefit from past CBM resource evaluated results, taking the nationwide 121 methane-bearing areas as evaluation units; emphatically considered factors of geological condition, resource and exploitation level, through multileveled screening and ordering have selected 41 CBM favorable areas. Using clustering analysis carried out classification for all 41 favorable areas selected. Through contrast and judging of CBM resource from classified blocks, optimized Qinshui, eastern Hubei, southern Hubei, southern Junggar, eastern Junggar, Yilan, Hunchun, Tiefa, Fuxin, Ningwu, Xishan, Jiaozuo, Huaibei, Songzao and Fengcheng totally 15 CBM exploration and exploitation favorable areas with CBM geological resources 4.47×10^12m^3in total area 50.7 thousand km^2 and above buried depth 1000 m.
