摘要
针对低渗透问题,给出了无量纲化的渗流控制方程、初始条件以及边界条件,并使用差分方法进行数值模拟。计算结果使用Gringarten Bourdet图版进行井底压力分析,给出了一种计算动边界位置的方法,并详细讨论了动边界变化情况。
The nondimensional control equations, initial conditions and boundary conditions of fluid flow in porous medium in low permeability reservoir are given, and the finite difference method is employed to simulate the fluid flow. Numerical results are archived by using Gringarten-Bourdet graph to analyze the well-bottom pressure. A method used to compute the positions of moving boundaries are presented and the propagation of moving boundaries are also discussed.
