核磁共振信号分析：解读流体含量、环境和孔径分布

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.
