【摘要】 成藏动力学系统是近几年在油气成藏研究中的一大热点,它以油气成藏的动力学机制和动力学过程为核心,探讨油气聚集和分布规律。本文在总结前人研究成果基础上,将金湖凹陷划分为3个成藏动力学子系统和5种油气输导体系,并利用流体包裹体恢复了成藏流体充注时间;根据油气运移聚集特征,总结出"下生上储"和"自生自储"两种成藏模式;从成藏条件出发,探讨了油气成藏主控要素。更多还原

【Abstract】 Dynamics of petroleum accumulation has been a hot issue in studying reservoir forming mechanism in recent years. Pool-forming dynamic system centers on the dynamic mechanism and process and thus aims at petroleum accumulation and distribution rules. On the basis of the previous studies in the Jinhu sag, three dynamic systems and five liaison systems are divided and the charging time of reservoir fluids is determined by using fluid inclusion techniques. Two models of reservoir formation are established according to the migration and accumulation characteristics. In addition, key factors controlling reservoir formation are discussed.更多还原
