The flow behavior of foam in pores affects the sweep range and displacement efficiency, it plays an important role in enhancing oil recovery. The numerical simulation method of foam transport in capillary tubes is summarized. The flow behavior of foam in capillary model was simulated and analyzed by Level Set method combined with gas-liquid two-phase flow. The Jia Min effect produced by the migration of bubbles from large channels to small channels is analyzed. The results show that the migration of foam in porous media can be replaced by a model of capillary tubes with different diameters. It will provide beneficial enlightenment for field application of gas-liquid dispersion system in profile control and enhanced oil recovery.
