摘要
建立了煤层气扩散渗流的微分方程 ,对煤层气渗流偏微分方程 ,采用差分法建立差分方程 ,进行了数值分析。所建立的煤层气扩散渗流模型较准确的反映了煤层中煤层气流动规律 ,对我国大面积低透气性无烟煤煤层气的开发具有一定的指导意义。
The paper established a differential equation of coal bed methane influent. The deviation differential equation of coal bed methane influent was digitally analyzed by difference equation with difference method. The established coal bed methane influent mode can correctly shown the coal bed methane flow law in the coal seam, which would have a certain guidance to the development of low penetration anthracite coal seam in China.
