Research on Oil-Water Interfacial Properties Effect of Polymer / Surfactant Binary Flooding System
The formula of surfactant(QY-3、SHSA-HN6、SS) and polymer compound system, and the interfacial characteristics between oil and water of Henan oil field were evaluated, the binary composite system formula adapt to the field was explored. The results show that the binary composite system (surfactant QY-3 and polymer 1630S) and oil-water in Henan can achieve ultra-low interfacial tension(＜10-3mN/m); If the addition agent NaCl was added to the composite system (Surfactant Ss and polymer ZL-Ⅱ or Surfactant Ss and polymer KYPAM) that the interfacial tension between oil and water can be reduced effectively.
