| 摘 要： | 在煤层气研究过程中,通过对曲线形态进行分析,认为在煤层气开采初期和中期,兰氏体积和兰氏压力越大,对产气越有利,而在开采后期,兰氏压力越小,对产气越有利.同时,也可根据曲线方程估算出煤层气采收率,进而获得煤层气可采资源量.

| Abstract: | During the study of CBM(coalbed methane),the result getting from the analysis of curve shape is that larger VL and PL are more favorable for gas production in the early and middle stage of CBM exploitation while smaller PL is more favorable for gas production in the later stage.Moreover,the extraction ratio of CBM can be estimated according to the curve equation,and then the recoverable reserves of CBM can be obtained. |
