沁水盆地上古生界致密砂岩储层特征

Characteristics of tight sandstone reservoirs in Upper Paleozoic of Qinshui Basin

沁水盆地是我国重要的含煤盆地,不仅其煤炭及煤层气资源丰富,在上古生界地层中还有大量页岩发育。本文通过扫描电镜、X-射线衍射、压汞实验等实验分析,对沁水盆地上古生界的致密砂岩储层特征进行了研究。

Qinshui Basin is an important coal-bearing basin in China. where coal and coalbed methane resources are abundant,but also a large amount of shale is developed in the Upper Paleozoic strata. In this paper,the characteristics of tight sandstone reservoirs in the Upper Paleozoic of Qinshui Basin aere studied by means of scanning electron microscopy,X-ray diffraction and mercury injection experiments.
