摘　　要：阐述了核磁共振微成象（ＮＭＲＩ）的方法原理，介绍了ＮＭＲＩ显示岩心内部结构、确定油水分布状态、观测流体驱替过程、了解岩石中孔隙流体局部流动速度、研究微观渗流机理等方面的应用。The principle of the nuclear magnetic resonance (NMR) microscopy isintroduced, experimental results obtained with NMR microscopy are reviewed. Various applicationsare sh own with examples. which include investigating the interconstructure in porous media and flowphenomena through porous media, rapidly and nondestructively visualizing the interconstructure ofrocks. determining oil and water distribution. estimating porosity. saturation and permeability. monitoring the procedure of fluid invasion. flow. and displacement through rocks, and quantitatively evaluating the efficicency of oil-recovery strategy in microscale view.
