摘　　要：昭通盆地上第三系褐煤资源丰富,在煤田地质勘探过程中,很多钻孔在钻遇煤层后出现气显示,预示昭通盆地上第三系蕴藏有较丰富的煤层气资源。本文从煤层气成藏条件入手,通过对气源、煤储层储集能力、盖层条件、构造条件、水动力条件的分析,同时结合煤储层含气性分析,对昭通盆地上第三系煤层气资源的勘探前景进行了初步评价。Shaotong Basin is rich in neogene lignite resources.During the process of geological exploration,gas emits from many boreholes when the drill rods enter into coal seams,which indicates the abundant CBM resources in the neogene system of Shantong basin.Started from the CBM reservoir condition,the paper analyzes the gas sources,capability of coal reservoirs and conditions of the covers,construction and hydrodynamic,and makes a preliminary evaluation on the exploration prospect of the neogene CBM resources in Shaotong Basin by anylizing the gas-bearing property of the coal seams.
