【摘要】 根据构造演化及沉积响应特征,利用钻井取芯、岩屑录井、测井资料以及高分辨率地震资料,将埕宁隆起北坡新近系划分为1个超长期、7个长期旋回层序。通过精确的层序地层划分及井震对比,建立了研究区新近系的等时层序地层格架。在此基础上,对层序发育的主控因素进行了探讨,认为构造沉降、全球海平面变化、气候变化、地形因素及河流类型是埕宁隆起北坡新近系层序形成与发展的主要控制因素。高精度层序地层划分及层序地层格架的建立对埕宁隆起北坡新近系岩性油气藏的勘探开发具有重要指导意义。更多还原

【Abstract】 According to the tectonic evolutionary history and stratigraphic and depositional characteristics,and based on drill cores,cutting logs,well logs and high-resolution 3-D seismic data,sequences including 7 third-order sequences are recognized for the Neogene System in the northern slope of the Chengning Uplift.Through high-resolution sequence stratigraphic division and the integration of well and seismic data,an isochronous stratigraphic framework is established.The dominating factors that controlled sequence development were discussed.Tectogenesis,global sea level change,paleoclimate,topographic features and river patterns are considered controlling factor in the formation of sequences.The high resolution sequence stratigraphic division has important implications for the exploration and research of petroleum reservoirs in the northern slope of the Chengning Uplift.更多还原
