The preparation of microemulsion from sodium dodecyl benzene sulfonate, sodium fatty alcohol ether sulfate, polyol and toluene by D phase emulsification was studied, and the influences of the quantitative ratio of the ingredients on the interfacial tension of the microemulsion were investigated by orthogonal experiments. The optimum formula was obtained as follows: w (polyop) 20%, solution 50 g, toluene 7 g and mixture of surfactant solution 31 g. The microemulsion's interfacial tension reached to 3.70 mN/m, and it is clear, transparent, thermodynamically stable and no phase separation occur even standing for a long time. The compounded oil expellent was prepared from this microemulsion, and the simulation application tests showed that it could enhance the productivity of oil by 18.06% and the recovery of residual oil by 29.97%.
