A numerical simulation of spin diffusion in inhomogeneous magnetic fields due to susceptibility contrast was developed to describe the transverse relaxation of fluids in porous media. The simulation results are in quantitative agreement with experimental measurements obtained on samples of simple geometry. They also confirm the interpretation of the 1H transverse relaxation observed in natural rocks either hydrophilic or hydrophobic for several deuterium oxide/oil saturations, based on the traditional description of water and oil arrangement.
为了描述多孔介质中流体的横向弛豫，开展了一项关于由磁化率对比度引起的非均匀磁场中自旋扩散的数值模拟。模拟结果与在简单几何形状样品上获得的实验测量结果在定量上一致。它们还证实了基于水和油排列的传统描述，对在几种氧化氘/油饱和度下的亲水性或疏水性天然岩石中观察到的1H横向弛豫的解释。
