Method for examining samples of frozen rocks

摘要

A sample of frozen rocks is placed into contact with a frozen solution of an X-ray contrast agent at subzero temperature. Upon the end of saturation of the sample, a computed X-ray microtomography of the sample is conducted at a subzero temperature. The obtained microtomographic image is analyzed and spatial distribution and concentration of ice and/or gas hydrate inclusions, as well as open and closed porosity are determined.

1. A method for studying frozen rocks comprising:
providing a contact of a sample of the frozen rocks and a frozen solution of an X-ray contrast agent at subzero temperatures, upon saturation of the sample of the frozen rocks with ions of the X-ray contrast agent scanning the sample by X-ray micro Computed Tomography at subzero temperatures, analyzing a micro-CT image obtained by the scanning and determining three-dimensional distribution and concentration of ice and/or gas hydrates inclusions and open and closed porosity in the sample.
