The results show that the amphiphilic polymer can substantially improve the profile control and displacing performancesof thefoam system,and itscontributionsare higher than those of the unitary foam system. In detail,it can effectively block the high-permeability reservoirs and obviously enhance the heavy oil recovery of the low-permeability layers.
