摘　　要：介绍了砂体形成过程数值模拟的基本特征,确立了数值模拟的控制方程,阐述了方程的主要数值解法。实例研究表明,在物理模拟与数值模拟给定条件基本一致的情况下,二者的冲刷及沉积特征具有较好的可比性,符合率在70％以上。The basic properties of numerical simulation of sandbody formation process are introduced, control equations are determined for the simulation, numerical solution for the equations is described. Case study shows that under the basic consistent conditions given for physical simulation and numerical simulation, both of them have better comparability of flushing and depositional properties, of which consistent rate is over 70%.
