【Abstract】 It is very important for secondary recovery and third recovery to determine residual oil saturation of high porosity, high Permeability, unconsolidated sand formation at high water cut stage because irreduclble water saturation is different at different development stage. In order to understand the changes of rock physical properties in detail and enhance the recovery factor, we have to think about the effect of decreasing irreducible water saturation on residual oil saturation.更多还原
