中文摘要：

通过对红阳煤田采集煤样的煤岩显微组分、煤级、煤相、煤岩显微裂隙分析和压汞孔隙结构测试,研究了该区的煤层气赋存地质条件、煤层气生气地质条件和煤储层物性特征。并采用基于GIS的多层次模糊数学评价方法计算了该区的煤层气资源量,预测了煤层气资源分布的有利区。结果表明,该区煤层气总资源量为217.87×108m3,资源丰度平均为1.54×108m3/km2,该区具有良好的煤层气资源开发潜力。其中,红阳矿的东南部及红菱-红阳的东南深部预测区,煤层累计有效厚度大,煤层气资源丰度高,煤储层物性较好,是该区煤层气勘探、开发的最有利目标区。

英文摘要：

Base on the analysis on coal and rock macerals, coal rank, coal facies, coal and rock micro fissures and pressurized mercury hole porosimetry test of the coal samples collected from Hongyang coalfield, the paper studied the coal bed methane(CBM) deposit geological conditions, coal bed methane formation geology, coal deposit feature in the area.The in-place CBM resource was calculated with the multi layer fuzzy mathematics assessment method base on GIS.The paper predicted the coal bed methane resource distri...
