FIELD: examination and analysis of materials. SUBSTANCE: specimen is prepared for examination, and its permeability is determined. Then specimen is centrifuged in different modes of centrifuge rotation. In this case, dependence of capillary pressure of draining of specimen effective pore space from water saturation and dependence of capillary pressure of absorption of specimen dynamic pore space from water saturation are determined. Normalized differential curves of dependence of radius occurrence frequency of pore channels from their size for dynamic and effective pore space are plotted by obtained dependences. Wettability parameter for definite radius of pores or their range is determined on basis of the above-indicated curves. EFFECT: higher results of analysis. 3 dwg
