摘要
基于吐哈盆地与粉河盆地(Powder River Basin)的煤层气地质资料,探讨了两盆地地质构造演化特征,对比分析了两盆地煤阶、煤岩、煤质、含气量及饱和度等物性条件,指出了吐哈盆地与粉河盆地在煤层气含量构成、渗透率及水文地质条件等方面的差异。
On the basis of studying the geologic data on coalbed methane (CBM) collected from the Tuha Basin in China and the Powder River Basin in America respectively, the geologic-tectonic evolution characteristics of the two basins are discussed; the petrophysical conditions of the coal rank, ingredient, coal quality, CBM content and saturation, etc., of the two basins are contrasted and analyzed; and the differences between the two basins in CBM composition, permeability and hydrogeological condition, etc., are pointed out in the paper.
