Abstract

Abstract

In this study changes of uncontinuous potential functions at the interface wereused to simulate the immiscible displacement in porous media. The elliptic partial differential equation was changed to a seven-pomt molecule form algebraic equation inthree dimensions using the finite difference method. The Strongly implicit procedure was adopted to determine the potential functions at every time instant. Then the change of interface was determmed. The simulation was continued until the displacement changed to unstable state. The effect of capillary pressure, wetting properly, and nonuniformity of permeability were consthered.
