摘要
南部F油藏的储层物性为带有倾角(18°)的低孔低渗挥发油藏,平均孔隙度为19.4%,平均渗透率为32.85×10-3μm2,油藏周围有丰富的CO2气源。为了研究该油藏注CO2可行性,开展了不同开采方式(衰竭,水驱,CO2驱,气水交替驱)长岩心驱替实验,并通过数值模拟研究进一步验证长岩心驱替实验结果。
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 μm^2 ,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.
