摘要
天然气水合物在海洋环境中与在纯水溶液中的生成条件有很大的不同。海洋天然气水合物的生成除了受温度和压力的影响外,还要受到孔隙水的化学组成、流体中气体的浓度及沉积物类型的影响。本文综述了国外海洋天然气水合物的实验研究成果及其进展,重点介绍了海洋天然气水合物生成与分解的热力学条件及各种影响因素,并探讨了今后该领域的研究方向和问题。
The conditions for gas hydrate formation in marine environment are very different from those in pure water. Besides temperature and pressure, the controlling factors for gas hydrate stability also include pore water composition, gas concentration in the fluid and marine sediment types in the seafloor. To study phase equilibrium conditions of gas hydrate in porous media is very important for scientists to understand the formation mechanism of marine gas hydrate, because it can provide information of formation/decomposition of gas hydrate. This paper summarized the new experimental results of marine gas hydrate, focused on the thermodynamic conditions and some factors for the stability of gas hydrate in marine environment, and also discussed some active aspects of laboratory methods to synthesize marine gas hydrate.
