摘　　要：基于全球典型的海域天然气水合物勘探成果,总结了传统油气与水合物烃源条件,并分析二者沿断裂垂向共生关系。研究表明,传统油气藏与天然气水合物藏在一定条件下存在气源共生关系,传统油气藏能为水合物聚集提供物质基础,水合物也可作为盖层为传统油气聚集提供遮挡。按照传统油气藏与水合物藏分布特征,可分为7种沿断裂垂向共生模式。Based on the results of gas hydrate exploration in typical sea areas around the world,this paper reviews and summarizes the source conditions of conventional hydrocarbon and gas hydrate systematically,and analyses their vertical symbiotic relationship along faults.The research shows that a source symbiotic relationship exists between the conventional reservoirs and gas hydrate reservoirs under certain conditions.Conventional reservoirs can provide material basis for hydrate accumulation,and gas hydrate can also be used as caprock to shield the traditional hydrocarbon accumulation.According to the distribution characteristics of conventional reservoirs and gas hydrate reservoirs,it can be divided into 7 vertical symbiotic models along faults.
