FIELD: chemistry.
SUBSTANCE: method includes pumping an X-ray contrast substance into a core sample, scanning the sample by X-ray tomography and obtaining histograms. The method is characterised by that the X-ray contrast substance in the core sample is a mixture of gelatine and an iodine-containing substance in concentration of not less than 10% by weight of the prepared solution.
EFFECT: high accuracy of determining spatial distribution in core material of effective pore space, and enabling investigation of structural features of the core after chemical or physical action.
