To solve the issue during deep heavy oil exploiting, a new Gemini surfactant is developed by Yangtze University, considering the excellent performance of anionic Gemini surfactant. The target product containing benzene ring is chosen. The emulsification and viscosity reducing test is conducted for oilfield G in western China. And the NP serial Gemini surfactants show excellent emulsifying and viscosity reducing performance in formation water with high salinity, which is suitable for deep heavy oil development with high bitumen content. This research has guiding significance for the development of heavy oil with high bitumen content.
