The natural gas hydrate is an ice-like crystalline substance formed by small-molecule natural gas such as methane and water under specific low-temperature high-pressure conditions. In terms of material composition, the formation process of the natural gas hydrate is an enrichment process of gas and pure water; from the distribution range, the natural gas hydrate can be widely formed in sea areas with certain water depth, deep lakes and permafrost zones; from the stability point of view, natural gas hydrates are relatively easy to form and decompose. The natural gas hydrate has high energy density, shallow burying depth, good condition of formed hiding and is clean and environment-friendly, and is an important strategic energy source and a potential future resource. At present, the research on the influence factors of the indoor synthesis experiment of the natural gas hydrate mainly focuses on a cooling mode, a depressurization mode, fluid properties and additives. Since the natural gas hydrate can not be maintained at normal temperature and normal pressure, the research on the physical properties of the natural gas hydrate is very difficult, many scientists concentrate on observing the formation and decomposition process of the natural gas hydrate under specific conditions by using instruments at the present stage, and few research on the physical properties of natural gas hydrate ore bodies and the influence of the physical properties on the exploration and development of the natural gas hydrate ore bodies is carried out.
