摘　　要：在沁水盆地煤层气储层已经总体上具有"先天"优势的情形下,从外在地质因素主控特征的角度,基于控制沁水盆地煤层气富集特征分异的关键地质因素——构造、热力场和水动力等的综合分析,对该盆地煤层气的富集类型划分进行了研究.研究结果表明,以沁水盆地构造区划特征为基础,沁水盆地的煤层气富集主要存在3种模式,可主要划分为6种富集类型,5个煤层气有利富集区域分别显现出不同的地质主控特征.In the situation that coalbed methane reservoir of Qinshui basin has already possed the ＂inherent＂ advantages, mainly considered key controlling characteristics of outside geological factors, then the classification of coalbed methane enrichment type was studied in this basin based on a comprehensive analysis of key geology factors which include structure, thermal field and hydraulic factors. These three factors cooperatively controlled the enrich- ment differentiation of Qinshui basin. The results show that there exists three primary patterns and can be divided into 6 enrichment types based on the structure belt division of Qinshui basin. The selected 5 favorable targets respectively show different geology controlling characteristics.
