Comparisons of static, quasi-static and dynamic 3D porous media scale network models for two-phase immiscible flow in porous media

摘要：

A dynamic 3D pore-scale network model is formulated for investigating the effect of in- terfacial tension and oil-water viscosity during chemical ooding. The model takes into account both viscous and capillary forces in analyzing the impact of chemical properties on ow behavior or displacement configuration, while the static model with conventional invasion percolation algorithm incorporates the capillary pressure only. From comparisons of simulation results from these models, it indicates that the static pore scale network model can be used successfully when the capillary number is low. With the capillary increases due to the enhancement of water viscosity or decrease of interfacial tension, only the quasi-static and dynamic model can give insight into the displacement mechanisms.
