摘要
煤层气的解吸、扩散是煤层气藏一个关键的内边界条件。本文应用数学方法通过对这一过程的刻划、描述，导出了有关煤层气解吸时间的概念，并提出了利用图解法确定煤层气解吸时间的方法，有助于在煤层气勘探。
The desorption and diffusion of coalbed methane are the key innerboundary conditions of coalbed methane reservoir.In this paper using mathematical method,the process of the desorption and diffusion was described,inferred the conception of coalbed methane desorption time and presented the graphics to determine the desorption time,would be very useful to recognize and determine that important parameter in coalbed methane exploration and development.
