In order to clear heterogeneous reservoirs waterflooding performance, and decreased interlayer and within-layer contradictions, and improved the water flooding recovery, experimental study should be conducted first, This paper based on Pucheng Sasan reservoir sandstone cores to study object. Multi-point pressure measurement of water flooding oil experimental apparatus was established. Through the three-layer water flooding experiment to study injection strategy, interlayer interference and recovery factors. True sandstone micro-model water flooding used newly developed color visual image analysis system researched water-drive types, forms of residual oil and waterflood efficiency. Percolation mathematical model was established, black oil simulation program was developed, long-core displacement experimental results were matched, pressure and saturation change were researched by the simulation matching results.
