摘要：

Two-phase fluid displacement in a two-dimensional porous medium has been studied experimentally and by simulations. A random porous medium was saturated with a wetting fluid (water/glycerol). A non-wetting fluid (air) was then slowly injected, forming a fractal invasion percolation-like structure. Shortly before breakthrough, the pressure of the wetting fluid was increased and the non-wetting fluid was forced to withdraw. The structure formed by the non-wetting fluid disintegrated into fragments. The displacement patterns were found to agree well with patterns obtained from simulations based on an invasion percolation model.
