摘要：

NMR T-1, T-2 and spectral linewidth measurements were conducted in rock samples with different saturations obtained by drainage experiments. Saturation dependent T-1 was found to follow a power-law relationship and the inverse of linewidth to follow a linear dependence with saturation. These phenomena can be explained by considering that the fluids are distributed in different sized pores for different saturation states, A method is proposed for calculating wetting phase relative permeabilities using T-1 data at various saturations.
