Abstract:

The research status of emulsification by using amphiphilic polymers in recent years has been reviewed, mainly including the effects of amphiphilic polymers of different structures on emulsifying properties. The effects of hydrophobic group, betaine group and compounded systems on emulsification have been introduced. The stabilizing mechanism of typical emulsions using amphiphilic polymers has been summarized. The percolation characteristics of emulsions containing amphiphilic polymers and the influence thereof on EOR have been analyzed. This review might provide theoretical foundation for how to enhance the emulsifying performance of amphiphilic polymers and for better understanding the role of emulsification in EOR mechanism. The development direction has also been pointed out.

Key words: amphiphilic polymer, emulsification, percolation characteristics, enhanced oil recovery, hydrophobic group
