| 摘 要： | 介绍了煤层气的吸附解吸特性，以及考虑吸附解吸特性的单相煤层气的扩散方程，并在该扩散方程拟稳态解的基础上，详细推导了单相煤层气的流动物质平衡方程，所得到的煤层气流动物质平衡方程可以有效确定单相煤层气储层的地质储量，同时也可以用来计算煤储层的渗透率。 |
| 关 键 词： | 煤层气 等温吸附 流动物质平衡 物质平衡拟时间 |

| Abstract: | This paper introduced adsorption and desorption character for coalbed methane,and diffusion equation for single-phase coalbed methane when adsorption and desorption character were considered,then the flowing material balance equation for single-phase coalbed methane was derived from pseudosteady state solution of the diffusion equation.By using the flowing material balance equation for single-phase coalbed methane,the OGIP could be exactly calculated,and reservoir permeability could also be calculated. |
| Keywords: | coalbed methane isothermal adsorption flowing material balance material balance pseudotime |
