摘要：

This study investigated the optimal concentration of an anionic surfactant (APA-H1) and a sulfonated polyacrylamide (SPAM-A5) formulation for SP flooding at high temperature high salinity conditions. IFT, viscosity and oil production rate in micromodel tests of the formulation were evaluated from 200 to 2000 ppm in high salinity water at 90 degrees C. Results showed by injecting 1000 ppm APA-H1 and 1,500 ppm SPAM-A5 with similar to 10(-4 )mN/m IFT and 5.4 cP viscosity, the highest incremental oil production was 27%, which were not improved by increasing chemical concentrations. The work reveals there exists an optimal range of surfactant polymer concentrations in SP flooding.
