In this paper,we take non / feminine compound HDS surfactant comprised of a new type of green surfactant alkyl poly glucoside and a-olefin ionic surfactant,evaluating experimentally the performances of the binary system formed from this surfactant and polymer composite(abbreviated as HDS binary system hereafter),such as interfacial tension performance,viscosity,stability and injection performance.Moreover,we implement systematical research to the oil displacement effect of the HDS binary system by indoor physical simulation experiments.The experimental results and study show that interfacial tension of the HSD single dosage and the HDS binary system with the crude oil from different plants,in a wide range of surfactant concentration,can reach rapidly 10-3 mN/m,an ultra low order;the viscosity and stability of interfacial tension are relative good;the system can improve the production rate more than 15 %.
