FIELD: measurement equipment.
SUBSTANCE: sample is previously frozen, a frozen sample under conditions of negative temperature is put in contact with a frozen solution of a radio-opaque agent, upon completion of sample saturation, computer X-ray microtomography of the sample is carried out under negative temperatures, and by means of analysis of the produced computer tomographic image they detect spatial distribution and concentration of ice and/or gas hydrate inclusions of open and closed porosity, distribution of pores by size, specific surface in the sample.
EFFECT: higher accuracy of assessment of characteristics of non-consolidated porous media.
