摘要
探讨了天然气水合物矿藏的形成条件和机理、水合物矿藏的聚集方式。天然气水合物的形成除了必要的气体和水,还需要一定的温压和地质条件;其形成机理可用高渗漏系统和弱渗漏系统来解释;天然气水合物在沉积物中主要以构造聚集和地层聚集的方式存在。综述了天然气水合物矿藏的识别方法。
Formation conditions and mechanisms as well as accumulations of natural gas hydrates(NGHs)are discussed.Besides essential gas and water,proper temperature,pressure and geological conditions are needed during the formation of NGHs;their formation mechanism can be explained by high and low gas flux systems;gas hydrate accumulations in sediment can be both structural and stratigraphic.How to discriminate NGHs is also suggested by the author.
