翻译核磁信号幅度与流体含量成正比信号衰减反映流体环境当体驰豫时间较慢、表面驰豫较强的时候驰豫时间T1或T2与SV流体接触孔壁面积流体体积成正比驰豫时间谱反映真实孔径分布。

The amplitude of nuclear magnetic resonance (NMR) signals is proportional to the fluid content, and signal decay reflects the fluid environment. When the longitudinal relaxation time is slow and the surface relaxation is strong, the relaxation time T1 or T2 is proportional to S/V (the wall area of fluid contact/the volume of fluid), and the relaxation time spectrum reflects the true pore size distribution.
