Abstract
Middle phase microemulsion flooding is an effective approach to improve reservoir recovery. Using orthogonal experiment, we obtain the preparation of middle phase microemulsion formula of oil displacement system. Scanning respectively SDS concentration, concentration of n-butyl alcohol and Na2CO3, we get the volume of the phase diagram and dissolve parameters figure. It can be seen: Vo=Vw, SPo=SPw, and achieved the best phase system. Contrast middle phase microemulsion in the best and surfactant flooding experiment after water flooding to improve oil recovery, the best middle phase microemulsion has obtained much better effects. The recovery ratio of Berea core by the best middle phase microemulsion and polymer solution system flooding after water flooding was raised about 44.5 percent, and the moisture content down to very low levels.
