In order to meet the oil displacement requirements of high temperature and high salinity reservoirs of Zhou16 well area in Jianghan oilfield，a kind of polyoxyethylene polyoxypropylene block polyether anionic-nonionic surfactant（PPS）was synthesized from phenol and styrene by etherification and esterification reaction. The interfacial tension，temperature and salt resistance， dynamic adsorption and oil displacement performance of PPS/alcohol ether sulphates（AES）compound system were studied. The results showed that the interface activity of compound system was good. The oil-water interfacial tension of PPS/AES compound system with 0.1% mass fraction and 1∶1 molar ratio could reach 1.39×10^-2 mN/m，and that remained at the order of 10^-2 mN/m after being treated at 140℃. The compound system had good salt tolerance. Under the condition of mineralization degree of 30×10⁴ mg/L or Ca²⁺ mass concentration of 3000 mg/L，the oil-water interfacial tension of the system maintained at the order of 10^-2 mN/m. The saturated adsorption capacity of compound system on the core surface was 0.097 mg/g sand，and the dynamic adsorption loss was less than that of a single surfactant. The compound system had better oil displacement effect. When the water content of water flooding in homogeneous core was 65% ，the maximum increment of oil displacement efficiency could reach 22.53% after transferring 0.4 PV PPS/AES at the injection speed of 0.05 mL/min. In heterogeneous core，the maximum increase of oil recovery rate of compound system was 19.8%. The PPS/AES compound system could be used for the oil displacement of Zhou16 well area in Jianghan oilfield.
