摘要: 煤层气藏的不均一性远比常规天然气藏明显。其源于煤储层岩石物理成分的极不均一、煤储层中孔隙系统的不均一以及外部封闭保存条件的改变。煤层气藏的普遍不均一性对煤层气勘探选区的评价有明显的影响,也会影响到勘探井网的优化部署。煤体几何形态、夹矸分布及煤相分析,不同煤相的煤储层孔裂隙系统分析,煤层气藏外部封闭分析等均为煤层气藏不均一性分析的重要内容。

Abstract: It is very clear that the heterogeneity of coalbed methane pools were much more obvious comparing with that of natural gas pools,which was resulted from the inhomogeneity of lithotypes of coal and its pore and fracture systems,the changes of surrounding rocks and the hydrology condition.There is much influences on evaluation of exploration strategy and selection of suitable well net for development because of the heterogeneity.The geometry of coal body,the partings and coal facies analysis,the pore and fracture system analyses and the trapping condition analysis are very important contents for study of coalbed methane pools.
