华北地区煤层气可采性的主要影响参数探讨

The Influential Parameters of Coal-seam Gas Recoverability in the North of China

摘要: 煤层气可采性是煤层气地质评价选区研究的重要组成部分，影响煤层气可采性的地质参数很多，其中较为重要的参数有煤层渗透率、相对渗透率、储层压力、煤层含气饱和程度等。文章对此进行了分析探讨，并得出结论：煤层渗透性是诸多影响煤层气可采性参数中最重要的地质参数，在煤层气可采性评价中应以煤层渗透性评价为重点。

Abstract: Coal-seam gas recoverability is a main component of coal-seam gas geologic evaluation. Geologic parameters that influence coal -seam gas recoverability include coal -seam permeability, relative permeability, coal reservoir pressure and gas saturation. It is believed that coal-seam permeability is the most important geologic parameter.
