This paper discusses the new progress and field application of CO₂ flooding in low permeability reservoirs enhanced oil recovery. The study shows that CO₂ flooding can improve the oil recovery rate of low permeability oilfield by more than 10%. The practice shows that the liquid CO₂ injection in low permeability reservoir is easier than water injection, and the reservoir generally has better CO₂ storage.
