摘要: X射线计算机断层扫描(X-ray computed tomography, X-CT)是一项无损分析物质空间结构的技术。随着对天然气水合物研究的深入, X-CT被广泛用于观察沉积物内部空间分布和测量孔隙率、饱和度、渗透率等物性参数。在反映多孔介质中天然气水合物的生成和分解方面, X-CT成像也具有实时、直观、准确等优点。重点从含水合物沉积物内部空间结构分析和水合物在多孔介质中生成与分解动力学过程两方面, 对国内外研究现状进行了综述。同时简要介绍了X-CT在水合物测量上的原理及使用的仪器类型, 并针对目前X-CT法研究水合物存在的不足, 对未来的研究重点和发展方向提出了建议。

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
