滇东—黔西地区晚二叠世煤岩及煤层气储层物性分析

A Physical Property Analysis on the Upper Permian Coal Rocks and the Coal-bed Gas Reservoir,Eastern Yunnan and Western Guizhou

本文以丰富的地质资料对滇东—黔西地区晚二叠世煤岩分布的割理 (裂隙 ) ,吸附、孔隙溶积、镜质组含量、含气性、灰分产率等进行了较为系统的研究 ,初步建立了煤炭与煤层气储层物性的关系 。

Systematic studies, using ample geologic information, were conducted on cleats (fissures), absorption, pore space, vitrinite content, gas-bearing parameter and ash productivity in the upper Permian coal rocks, eastern Yunnan and western Guizhou. The physical property relation between the coal rocks and the coal-bed gas reservoir was established primarily, the coal rocks patterns with high vitrinite content were suggested to possess desirable condition for physical property of coal-bed gas reservoir.
