For the problems such as not synchronized theory and practice of heavy oil reservoirs and not clear mechanism of profit differentiate, combined with the experimental results of the actuating pressure gradient, we can use the experimental data fitting the coefficient of drag. Using the method of numerical calculation, we analyze the influx law of the viscosity of oil, the pressure gradient, the block, and the density of oil on microcosmic flow especially. Finally by comparing the distribution of oil and water phase under different influential factors, we display the law for the oil-water differentiation microcosmic flow of heavy oil directly. Research results can provide reference for revealing the mechanism of heavy oil profit differentiation, and contribute to EOR of heavy oil reservoirs.
