摘要
Two reservoir cores and one synthetic alumina sample have been quantitatively studied by means of proton, spin-lattice relaxation of the bulk samples, and by 2D-FT slice selected imaging. T1 and M0 images of high quality have been obtained with reasonable data acquisition and data processing times. T1 and T2 relaxation processes have been shown to be correlated, and possible causes for the differences between average image T1 values and those measures for the bulk samples are discussed. Variation of T1 within the images is discussed in terms of the contributions from pore size and surface relaxation effects.
