Application of modern instruments measurement techniques for hydrate research

Abstract

The characterization of natural gas hydrate samples is significant for us to know the property, distribution, and dynamic process of gas hydrate formation in sediments. Various advanced modern instrument test techniques can provide technical support for hydrate researches. However, these advanced techniques have many exclusive features because hydrates cannot exist in a stable form at normal temperatures and pressures. This chapter is concerned with the application of X-ray computerized tomography (X-CT), X-ray diffraction (XRD), nuclear magnetic resonance (NMR), high-pressure differential scanning calorimeter (high-pressure DSC), atomic force microscopes (AFM), and neutron diffraction (ND) to hydrate measurement and identify its potential prospects.
