摘　　要：将特征有限元方法和混合有限元方法进行耦合,对页岩气藏渗流模型进行了数值模拟,给出了详细的误差分析,得到了最优的L^2模误差估计,并用数值实验验证了方法的有效性.. In this paper characteristic finite element method and mixed finite elementmethod are coupled to simulate the shale gas seepage model.A detailed error analysis isgiven and an optimal error estimation of the L2 norm is obtained. Finally, the rationality ofthis method is verified by two numerical experiments.
