摘要: A method for determining an earth formation property from nuclear magnetic resonance measurements includes applying suppression functions to spin echoes in at least one burst measurement set produce a modified data set, the suppress contribution of having non-negligible polarization correction; inverting and standard echo parameter distribution, being acquired on sample; computing distribution. The selected longitudinal relaxation time, transverse ratio time diffusion constant.
