本文分析了济阳坳陷第三系隐蔽油气藏勘探历程,将第三系隐蔽油气藏分为三类(岩性油气藏,地层油气藏及裂缝性油气藏)八种,总结了隐蔽油气藏的一般特点及其发现规律,建立了陡坡式、洼陷式、中央背斜式及缓坡式四种隐蔽油气藏聚集模式。从储层地质建模、圈闭识别描述、油藏综合评价等方面阐述了隐蔽油气藏的主要勘探技术。
This paper analyzes the exploration process of the Tertiary subtle reservoirs in the Jiyang Depression. The Tertiary subtle reservoirs are divided into three types (lithologic reservoirs, stratigraphic reservoirs and fractured reservoirs), and the subtle reservoirs The general characteristics and the discovery rules of the four subtle reservoirs are established, which are steep slope, depression, central anticline and gentle slope. The main exploration technologies of subtle reservoirs are elaborated from the aspects of reservoir geological modeling, trapping identification and reservoir comprehensive evaluation.
