摘    要:通过对煤层气赋集成藏因素和机理的分析,结合煤层气勘探中有煤层却没有煤层气赋集,有煤层气赋集未必是勘探的有利选区等地质认识,探讨了煤层气藏的概念,并根据煤层气藏的成因和构造形态对煤层气藏类型进行了详细划分,共划分了8种煤层气藏类型,包括了目前所有已经发现煤层气藏类型。并认为只有在含气饱和度较高的煤层气藏,且具有较高的渗透率,才能成为煤层气勘探的有利区块。

关 键 词:煤层气  成藏  富集  分类

Abstract:From the exploration activities, we can make the conclusions that we can find coal but no methane and area with little methane accumulation is not favorable. The concept of coal bed methane accumulation was brought forward on the basis of the analysis of accumulating factors and mechanism. Coal bed methane trap was divided into six types in terms of the cause of formation and tectonic shapes, which basically included the all coal bed methane types prospected till now. Only in coal bed methane accumulation area with higher saturation and permeability is the favorable area for coal bed methane exploration and development.
Keywords:coal bed methane  accumulation  concentration  classification
