| 摘 要： | 低渗透油藏开发面临注水困难或注水开发效果差的问题,而注气驱是动用此类难采储量的有效方法之一。室内实验结果表明:特低渗透岩心水驱效果好于气驱效果,而超低渗透岩心的结果相反,同时,注N_2的效果优于CO_2的效果。

| Abstract: | In low-permeability oil reservoirs,the efficiency of oil recovery with water flooding process is poor or it's development faces the problems of water injection difficulty.The experiment results in laboratory showed that the water flooding is better than the effect of gas driving in the low permeability core,and the result of the ultra-low permeability core is contrast,at the same time,the effect of N_2 driving is better than the effect of CO_2. |
