摘要
本文从煤成气资源评价的角度,较详细地叙述了两淮煤田石炭二叠纪含煤岩系所含砂岩、泥岩、石灰岩和硅质岩的成分、结构、构造及厚度和形态特征,特别是结合储集层及盖层的物性进行了评述。
As viewed from the evaluation of coal-generated gas resources, a fairly detailed presentation is conducted of the composition, texture, structure, thickness and morphological features of the sandstone, mudstone, limestone and silicastone of Carboniferpus-Permian coalbearing rock formations in Huainan-Huaibei Coalfield. A special discussion is made of the physical properties of gas reservoiring and covering strata. And finally a brief account is given of the sedimentary environments of each coalbearing formation and member
