摘要
本文根据煤的储气特征、煤层气的吸附特征、排水降压解吸产气机理建立了煤层气藏数学模型和三维全隐式差分模型，采用最佳变松驰求解，收敛度快，稳定性好。
This paper has established a mathematical model and three dimension full implicit difference model of the coalbed gas reservoir from the container gas feature of the coal,the adsorption feature of coalbed gas,the mechanism of the water drainage,the pressure decline,the adsorption and the producting coal gas.The Optimal variable relaxation method has been used. It is of quick convergence and good stability.
