COMPUTER SIMULATION OF FLUID IN PORE MEDIUM AND PORE STRUCTURE WITH CONTACT PROCESS THEORY

为了显示孔隙介质中渗流行为的微观变化 ,了解孔隙的连通性 ,应用基本接触过程的理论 ,建立了数学描述方法。从而可对连通孔隙随距离的变化情况进行仿真 ,显示孔隙最大连通距离。其结果可用于油气采出范围的预测和计算 。

In order to visualized fluid seepage action and pore microcosmic structure and connection in pore medium,a mathematical model was presented in this paper.With the contact process theory,seepage process and pore structure was simulated with computer.The model and simulation can be used to calculate the longest distance of fluid seepage in pore medium.The results of model and simulation can evaluate the range of oil or gas exploitation,and also the area of injected fluid sweeping.In addition,the model and simulation can provide data for oil or gas exploitation and fluid injection control.
