Abstract
This paper discusses the new progress and field application of CO 2 flooding in low permeability reservoirs enhanced oil recovery. The study shows that CO 2 flooding can improve the oil recovery rate of low permeability oilfield by more than 10%. The practice shows that the liquid CO 2 injection in low permeability reservoir is easier than water injection, and the reservoir generally has better CO 2 storage.
