摘要

•The porosity difference between NMR porosity and water porosity was explained.•Relaxation times of capillary-bound water were ranging from 0.12ms to 6.12ms.•A novel method of characterizing fluids by 1D T2 spectrums was developed.•Identification graph of hydrogen-bearing phases by using a 2D T1-T2 map was made.
