Abstract:

The measurement procedure is described for the function of micro- and nano-pores size distribution by NMR- relaxometry during the heating of a pre-frozen, water-saturated sample of porous medium (core). The experiments in temperature and time measurements of water bulk relaxation are performed on a naturally-occurring sample, and provide support for measurability of the distribution function of pores with a diameter of less than 100 microns in sizes in relaxation spectrum.
