Pore-Scale Simulation of Water Flooding Using Volume of Fluid Method

Water flooding is a commonly used method in oilfield development, and the water process essentially of oil-water movement porous media. Pore-scale flow law can guide development plan, to improve oil recovery efficiency. In this paper, computational domain constructed from CT scan images real cores. The pore structure simulated using interFoam solver OpenFOAM. influence displacement distribution remaining analyzed three aspects: cut curve, state same injection amount, final state. rate velocity affects swept range, factor increases gradually with increase rate. With different velocity, sweeping sequence pores different, location shape are very different. Due dominant forces under wettability states, patterns core also
