摘要
煤层既是煤层气的源岩又是储集层,煤层气从煤层中的解吸受众多因素影响,其中煤层的储层特征就是其重要影响因素之一。文中从煤储层的孔隙结构特征、渗透性、储层压力、埋藏深度、温度、水分、煤阶和煤岩显微组分等方面,分析了它们对煤层气从煤中解吸的影响,力求为煤层气解吸机理研究和煤层气开采提供一定的理论支持。
The coal bed is not only the source - rock but also the reservoir of coal - bed methane. The desporption of coal - bed methane from coal beds is affected by many factors, in which the reservoir characteristic of coal beds is one of the most important factors. This paper analyzed the effects on coal - bed methane desporption from reservoir characteristics, including pore structures, permeability, reservoir pressure, burial depth, temperature, water, coal rank and microscopic components of coal rock., which could provide a theoretical support for researches on the desorption mechanism and the exploitation of coal - bed methane.
