Abstract: Aiming at weak formation adaptability and limited temperature resistance of common polymer/surfactant system,which largely limits its application in low-permeability,high-temperature and high salinity reservoir, a binary flooding system was established based on the combination of polymer and anionic-nonionic surfactant. Through laboratory experiments,the performances of the binary flooding system were studied,such as viscosity, interfacial tension,aging stability,adsorption capacity,chromatographic fractionation effect and oil displacement efficiency. The results show that the interfacial tension between the system and the crude oil could be lowered to 10-3 mN/m while maintaining excellent stability. The saturated adsorption value of the binary flooding system is much lower than that of single system. Meanwhile,the effective distance of ultra-low interfacial ten-sion of surfactant extended from 19% to 27%. However,the chromatographic fractionation effect was not negligible. The binary flooding system,which is 0.4 PV (1 000 mg/L HF62208+0.3% NPAC),can increase oil recovery by 11% on natural core with permeability of 18.6-62.5 mD from A oilfield, indicating excellent EOR performance for low-permeability reservoirs.
