摘　　要：从济阳坳陷新近纪的构造活动、地质特征、沉积充填方式及与古近纪构造地质特征的对比分析等方面入手,首次对新近系构造单元进行划分和命名,共划分为坳缘超覆带、浅凹带、缓坡带和披覆构造带4个构造带,总结了各个构造带的构造组合样式,并从研究新构造运动与晚期成藏的关系、指导不同构造带油气勘探等方面阐述了其石油地质意义。This paper starts with the structural movement, geological features, sedimentary filling models during Neogene and their correlation with the structural geological features during Paleogene, dividing and naming the structural units during Neogene for the first time. All the units are divided into four zones, i.e., the overlapped zone with trough margin, the shallow sag zone, the gentle slope zone, and the drape structural zone. The structural styles of all structural zones are concluded. The significances of petroleum geology of the division are illustrated from the perspectives of the relationship between neotectonic movement and late reservoir formation and the guidance for oil and gas exploration in different structural zones.
