O2驱油过程两相相对渗透率及毛细管压力曲线预测方法研究
pplication of MRI for investigating relative permeability and capillary pressure curve in porous media during water flooding and following CO2 flooding
将CO2注入枯竭或低渗透油藏是实现提高采收率及解决温室气体地质埋存的有效方法,为了有效评价CO2驱油效率，必须对多孔介质中CO2-油两相渗流规律进行深入研究。应用磁共振成像（MRI）技术实现了多孔介质内两相渗流过程的可视化检测，获取不同时刻、不同位置、各相流体的饱和度分布，并根据两相流体渗流基本方程，探讨了利用毛细管末端饱和度曲线预测CO2-油两相相对渗透率和毛细管压力的方法。
Injecting CO2 into exhausted or low permeability reservoirs is an effective method to improve oil recovery and to solve the greenhouse gas geological storage. In order to effectively evaluate oil displacement efficiency of CO2, the law of two phase flow of CO2 in the porous media must be studied. Magnetic resonance imaging (MRI) is applied to implement the visualization of two-phase flow in porous media, for different times, different locations, the saturation distribution of each phase is obtained, and according to the basic equation of two phase fluid, the end of the capillary saturation curve is used for the prediction of CO2 - oil two phase relative permeability and capillary pressure.
