【摘要】 青东凹陷是济阳坳陷的一个次级构造单元 ,位于渤海浅水海域。该凹陷主力油源层埋藏浅 ,成熟度低 ,人们对其勘探潜力认识不足。文章对青东凹陷石油基础地质条件进行了综合分析 ,认为其深洼区烃源岩已经成熟 ;并提出凹陷构造运动微弱 ,保存条件较好 ,以及油气近距离成藏等新认识 ;经研究认为有利勘探区域为靠近生油中心的各类构造和地层圈闭更多还原

【Abstract】 Qingdong sag is a secondary structure unit of Jiyang depression and lies in Bohai shallow sea waters. The knowledge of exploration potential in the sag is not enough for shallow burial depth and low maturity of main source rock bed. Basic geology conditions of the sag are analyzed comprehensively, and the source rocks in deep depression area are thought of mature. Understanding of weak tectonic movement, good preservation and near?range pool?forming is suggested. It can be seen that favorable exploration areas are stratigraphic traps and various types of structures near oil generation center.更多还原
