摘要(Abstract)：

本文把ＴＶＤ格式引入油藏模拟，给出了数值求解两相渗流方程组的ＴＶＤ差分格式，并讨论了相应的ＴＶＤ条件。在此基础上对目前流行的商业软件ＶＩＰ黑油模拟器中的流度上游权格式进行了二阶校正。数值算例表明，使用ＴＶＤ格式求解两相渗流问题比使用传统的流度上游权格式有较高的精度，且少用可观的计算机内存和ＣＰＵ时间。
This paper introduces the TVD format into reservoir simulation,gives the TVD differential format of numerically solving the two-phase seepage flow equation group,and discusses corresponding TVD conditions.On this basis the second order modification has been conducted for the mobility upstream weight format in currently popularly commercial software,the VIP black oil simulator.Examples calculated numerically indicate that use of the TVD format is more accurate in solving the two-phase seepage flow question than traditional use of the mobility upstream weight format is,and uses less considerably internal storage of a computer and CPU time.
