摘要: 煤层气是一种非常规天然气资源。煤层气有两种赋存状态:吸附在煤颗粒表面的吸附气;悬浮在微孔隙中的游离气。本文根据吸附气和游离气的物理状态阐述煤层气地质储量的计算和主要参数的确定方法。Abstract: Coalbed methane, a kind of non -conventionalnatural gas resource,have two existing status: adsorbed gas on surface of coal grains and suspended gas in micro - pores. Methods of calculating coalbed methanegeologic reserves and of dctcrmining the main calculationparameters are given in this paper on base of physicalstatus analysis of adsorbed gas and free gas.
