| Abstract: | A kind of high-activity ,good salt and heat resistance ,ultra low interfacial tension oil displacement agent （CS-6） was synthesized by using the 12-alkyl betaine/fatty acid amide surfactant .The results of the properties of the surfactant system showed that the interfacial tension of oil-water could be reduced to 10-4 mN/m when the salinity 10 000~100 000 mg /L ,the concentration of the surfactant 0 .3% ~0 .6% and the temperature 40 ℃ ~80 ℃ .The surfactant system has good emulsification and adsorption stability .The displacement simula-tion experiments have good effects . |
