FIELD: test equipment.SUBSTANCE: frozen rock specimen is brought in contact with frozen solution of X-ray contrast agent under negative temperature conditions. After saturation of the specimen is completed, computer-aided microtomography of the specimen under negative temperatures is performed, and using the analysis of the obtained computer-aided tomographic image, spatial distribution and concentration of ice and/or gas hydrate inclusions, as well as open and closed porosity is determined.EFFECT: providing visualisation of ice or hydrate formations in porous space of frozen rocks due to improving their contrast ratio, which allows carrying out evaluations of spatial distribution and concentration of ice and gas hydrates in porous space of rocks, as well as evaluation of open and closed porosity by means of analysis of X-ray images.11 cl, 5 dwg |
