【Abstract】 The relative permeability curves and residual oil saturation are important parameters that describe multi phase flow in multiple media and they can also offer base information of each phase’s flow in oil reservoir. Whether the temperature could affect the relative permeability and residual oil saturation was discussed in this study. Simulating the reservoir condition with samples of unconsolidated sandstone and crude oil helps determine the temperature effects on relative permeability and residual oil saturation. Water flooding tests were conducted under 60℃, 120℃, 200℃ with crude oil samples from Du32, Qi 40 Liaohe Oilfield of eastern China and Area 6,Kelami Oilfield of northwest China, and whereupon the experiment results are processed and analyzed. The conclusion is that the temperature has little effect on the relative permeability curve and residual oil saturation.更多还原
