Abstract:

Amphiphilic polymers, with their excellent thickening and emulsifying properties, have been gradually applied in the field of enhanced oil recovery. The mechanism of enhanced oil recovery by amphiphilic polymers was summarized from the aspects of enhancing sweep efficiency and displacement efficiency. The recovery efficiency of amphiphilic polymers under different injection modes was investigated, including injection slug size and injection timing. Finally, the potential of enhanced oil recovery for the three types of synergistic systems was discussed. The research results could provide guidance for the evaluation and prediction of the recovery efficiency of amphiphilic polymers in the oilfield.

Key words: amphiphilic polymer, enhanced oil recovery, injection mode, synergistic system
