Abstract
The orthogonal-test-design method was used to determine the optimum prescri ption of middle-phase microemulsion for tertiary oil recovery. The results indicate that in the petrolium sulphonate(PS) - the mixed alcohols(iso-prop anol and n-butanol) - mineral water(7000ppm) - simulating oil(kerosen with 5.0% crude oil added) system, the optimum composition of the middle-phase m icroemulsion contains 2.0%PS and 2.2% the mixed alcohols(the weight ratio b etween iso-propanol and n-butanol is 9.1). The values of solubilization par ameter, interfacial tension, and efficiency for oil recovery are 11.5ml/g, 3.30x10(-4)mN/m, and 94.6% respectively for the optimum flooding system.
