ИСТИНА

A samples of an unconsolidated porous medium is frozen and subzero temperature is placed into contact with a frozen solution of a X-ray contrast agent. Upon the end of saturation of the sample, X-ray computed microtomography of the sample is conducted at a subzero temperatures and by means of analyzing the obtained computer tomograhic image, spatial distribution and concentration of ice ans/or gas hydrate inclusions, open and closed porosity, pore size distribution, specific surface in the sample are determined.
