Abstract:

Amphiphilic polymers have achieved a certain oil-increasing effect in oilfield applications due to their good temperature resistance, salt resistance and crude-oil-emulsifying properties. In order to further understand the application effects of amphiphilic polymers in oilfields, the application examples in domestic and foreign oilfields and the physical and chemical properties of amphiphilic polymers have been introduced. The adaptability of the amphiphilic polymers and their synergistic systems to the reservoir has been reviewed in terms of reservoir type (heavy oil reservoir or thin oil reservoir), reservoir temperature and reservoir salinity. Finally, based on the application conditions, the development trend of the amphiphilic polymers and their synergistic systems in the future has been pointed out.

Key words: amphiphilic polymer, reservoir environment, temperature, salinity
