山东惠民凹陷沙四段上亚段层序地层与沉积特征
|
摘要
应用层序地层学方法,通过钻井、测井、地震反射等标志,将惠民凹陷沙四上亚段划分为1个三级层序,并以地层叠置样式、岩性、岩相的变化细分为低位、湖侵和高位3个体系域;在连井剖面层序对比的基础上建立起研究区沙四上亚段层序地层格架。通过岩芯、钻井、测井、古生物等资料的分析识别出沙四上亚段主要发育扇三角洲、近岸水下扇、浊积扇、三角洲、滩坝、湖泊等沉积体系,并建立了不同构造带的沉积模式。首次系统分析了惠民凹陷沙四上亚段沉积相的构成、演化与分布规律,并预测了有利沉积相带,这对指导研究区隐蔽油气藏的勘探具有重要意义。
The Upper Submember of the 4th Member of the Shahejie Formation in Huimin Depression represents one third-order sequence according to sequence stratigraphic analysis based on well log and seismic reflective data.Lowstand,lacustrine transgressive and highstand systems tracts can be recognized based on the stacking patterns and changes of lithology and lithofacies.The sequence stratigraphic correlation of well-tie sections made it possible to construct the regional stratigraphic framework.Fan delta,near-shore underwater fans,turbidite fan delta,beach bar and lake sedimentary system facies can be identified using core,drilling,logging,and paleontological data.The sedimentary mode of these structural zones is established.The architecture,evolution,distribution of sedimentary facies of the upper Es_4 in Huimin Depression are analyzed,The favorable sedimentary facies is predicted,These results have great significance in the identification of subtle traps in this depression.
