METHOD FOR EXAMINING SAMPLES OF UNCONSOLIDATED POROUS MEDIA

A sample of an unconsolidated porous medium is frozen and at subzero temperature is placed into contact with a frozen solution of an X-ray contrast agent. Upon the end of saturation of the sample, X-ray computed microtomography of the sample is conducted at subzero temperatures and by means of analy...

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