江苏南部地区煤层气资源

Coal Bed Gas Resources in South Jiangsu

根据江苏南部地区二叠系龙潭组煤系的分布和规模、煤矿瓦斯涌出特征、煤的产气能力、煤层的储集条件等煤层气地质条件综合研究工作 ,认为该区煤层气资源存在一定的勘探开发前景 ,对各典型含煤区块煤层气综合评价出有远景区 (A类 )、较有远景区 (B类 )和远景差区 (C类 )。

The research is based on the overall coal bed geological conditions including the distribution and scale of the coal system in Longtan Formation of Permian system, outflow characters of the coal gas, gas productivity of the coal and the gas-bearing conditions of the coal beds. It is concluded that the coal bed gas resources in the studied area is perspective in terms of exploratory development, and three classes of perspective zones(fine, preferably and poor) are evaluated in the lights of each typical coal-bearing block.
