摘　　要：在边缘海盆地油气研究中,古潜山型油气藏研究相对薄弱,应用层序地层学方法进行古潜山油气成藏预测将对边缘海盆地油气勘探起到积极的指导作用。珠三坳陷是一个断裂系统十分发育的箕状断陷盆地,它的形成和演化受到断裂的强烈控制。在坳陷内主干断裂的控制下,坳陷分割为文昌A凹等9个构造单元,其中,文昌A、B、C凹陷为生油凹陷。位于文昌C凹西部的古潜山可以得到来自3大生油凹陷的油气供给,具有较好的储盖条件,可以发育潜山披覆油气藏和潜山内幕油气藏2种油气藏类型。In the research of marginal basin oil and gas reservoir,buried hill oil and gas reservoir was studied.It was of great significance to study buried hill on the marginal sea basin by sequence stratigraphy.Zhu Ⅲ Depression was a dust-like rift basin,in which the fault systems ware well-developed.Its formation and evolution were intensely controlled by the tectonic.Under the control of the trunk faults,the depression is divided into nine tectonic units,such as Wenchang Sag A,Wenchang Sags A,B,C are the source rock sags in the Zhu Ⅲ Depression.The oil and gas of buried hill located in the western of Wenchang C Depression could come from three source depressions,and also there are good reservoir and cap conditions.Therefore two reservoirs are developed,they are overlap-buried hill oil and gas reservoir and reservoirs inside buried hill.
