Abstract

Abstract: This paper gives a review of the application of X-ray computed tomography (X-CT) in natural gas hydrate research, emphasizing sediment structure analysis and dynamics process. X-CT is a non-destructive technique, which is used to analyze the spatial structure of an object. For in-depth study of natural gas hydrate, X-CT plays an increasingly important role in observing the interior spatial structure of natural gas hydrate sediments and assessing the physical properties of these sediments, such as porosity, saturation, and permeability. In terms of identifying natural gas hydrate formation and dissociation process, X-CT imaging has the advantages of being real-time, intuitive and accurate. The measuring principle, apparatus and the important aspects for future hydrate research based on X-CT are also discussed.

Key words: X-ray computerized tomography, natural gas hydrate, porous media, physical properties, X-CT imaging
