摘要
本文论述了多孔介质中流体的扩散特性，论述了ＰＦＧ－ＮＭＲ扩散测量方法和ＣＰＭＧ－ＮＭＲ扩散测量方法，相应的扩散系数计算方法。
his paper presents the fluid diffusion character in the porous media ″PFG-NMR″ and ″CPMG-NMR″ diffusion measurement method and the diffusion coeffieient computation method,the speciality of each measurement method,and the measurement application are all discussed here
