摘要：For water flooding heterogeneous reservoir, the reasonable formation pressure, injection pressure and flow pressure were studied, under different injection speed conditions. Through research we can see: (1) When the formation pressure is maintained near the saturation pressure, the recovery rate is the highest and the development effect is the best; (2) When the water flooding injection rate is 0.10PV/a, reasonable flow pressure range of (4.0-5.5) MPa, reasonable injection pressure range of (10.5-12.0) MPa. When the water flooding injection rate is 0.15PV/a, reasonable flow pressure range of (3.5-5.5) MPa, reasonable injection pressure range of (11.5-13.0) MPa. When the water flooding injection rate is 0.25PV/a, reasonable flow pressure range of (3.5-4.0) MPa, reasonable injection pressure range of (13.0-14.0) MPa; (3) By controlling the reservoir pressure, the injection pressure and the flow pressure, the pressure distribution is maintained within a reasonable range, and the streamline distribution is more uniform and the recovery rate can improve 1.34%.
