摘要：

Multiphase flow properties are frequently affected by the saturation history followed by the fluids up to their actual condition. In this work we evaluate the effect of rock wettability and its geometry on fluid saturation trajectories for imbibition and drainage processes. The reservoir rock is described by a fractal pore type model. By using the method of characteristics, we determine the region in the saturation space where the different displacement sequences take place. A strong dependence between the area associated to the saturation trajectories, the wetting condition of the rock, and its fractal dimension is found. These results allow us to quantify the impact of rock geometry and wettability on displacement hysteresis phenomena as observed in natural porous media.
