Based on the quartet structure generation set, the porous media with random distribution are constructed. The lattice Boltzmann method is used to simulate the mesoscopic migration of oil and water in porous media. Then the distribution law of oil and water velocity and pressure in porous media is analyzed, and the fitting equations of oil and water resistance coefficients are obtained under different porosity. The results show that when the oil and water migrate in porous media, the viscous resistance coefficient is larger than the inertia resistance factor, and the viscosity resistance coefficient of water is obviously higher than that of oil, while the coefficient of inertia resistance of oil and water is nearly same.
