| Abstract: | 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. |
