F reservoir in southern China is a volatile reservoir with low porosity and permeability and a dip angle of 18°,in which the average porosity and permeability are 19.4% and 32.85 ×10 -3 μm2 ,respectively.The reservoir is sur-rounded by rich CO2 source.In order to study on the feasibility of CO2 injection for enhanced oil recovery,long -core flooding experiments have been conducted on different development scenarios including depletion development,water flood-ing,CO2 flooding,CO2 alternating water flooding.And the results have been further verified by numerical simulation.
