摘要
油气运移、聚集史软件的功能是重建盆地发育中油气资源运移、聚集的历史．其数学模型是一组非线性耦合偏微分方程组的动边值问题．本文对二维、有界区域的一般情况，提出一类特征混合元逼近并得到了逼近解的最佳阶L2模误差估计．
The software for Oil-Gas transport and accumulation is to describe the history of Oil-Gas transport and accumulation in basin evolution. It is of coupled system of nonlinear partial differential equations with moving boundary value problem. For a generic case of 2dimension and bounded region, we put forward a kind of characteristic mixed finite element approximation, and derives from them optimal order estimates in L2 norm for the error in the approximate solution
