摘　　要：本文采用修正迎风差分方法处理多孔介质中两相完全可压缩可混溶驱动问题,建立了差分计算格式,并证明了格式的收敛性,同时得到l2和h1误差估计,最后数值试验证明了方法的有效性。The modified upwind difference method is adopted to treat the two-phase entirely compressible miscible displacement in porous media. The difference scheme is formulated and its convergence is proved, the I2 and h1 error estimates are derived simultaneously. Finally, numerical experiment shows the efficiency of the proposed method.
