摘要：

Based on cationic and anionic surfactant mixed systems, ultra-low interfacial tension was achieved in the Karamay oil field systems. Upon the addition of a non-ionic third component, the solubility of the mixed cationic-anionic surfactant systems increased significantly. The mixed surfactant ratio and the concentration were determined by the application in the five areas of the Karamay oil field. The interfacial tension in some real systems was found to be around 10(-4) mN center dot M-1. These cationic and anionic surfactant mixed systems have a super-resistance adsorption capacity. The results show that after 72 h of quartz adsorption, these systems can still reduce the interfacial tension to an ultra-low level.
