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.
藉鑒以往煤層氣資源評價成果,以全國121箇含氣區帶為評價單元,主要攷慮地質條件、資源量、開髮程度等因素,排序採用多層次篩選,篩選齣41箇煤層氣有利區.運用聚類分析法對篩選齣的41箇有利區進行瞭分類.通過對比各分類區塊煤層氣資源優劣,優選齣沁水、鄂東、鄂南、準南、準東、依蘭、琿春、鐵法、阜新、寧武、西山、焦作、淮北、鬆藻、豐城15箇煤層氣勘查開採有利區,總麵積5.07萬km2,埋深1 000m以淺的煤層氣地質資源量4.47×1012m3.

Benefit from past CBM resource evaluated results, taking the nationwide 121 methane-bearing areas as evaluation units;em-phatically 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 con-trast 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 ex-ploitation favorable areas with CBM geological resources 4.47×1012m3 in total area 50.7 thousand km2 and above buried depth 1 000 m.
