| 摘 要： | 在高分辨率三维地震、钻井以及大量地质资料研究基础上,根据层序地层界面特征,将南堡凹陷东营组划分为1个二级层序和4个三级层序。以初始洪泛面和最大洪泛面识别特征为依据,进一步将三级层序划分出体系域。通过层序地层格架特征及其发育位置分析,认为柳南次凹层序地层格架发育的主控因素为构造、物源和湖平面变化。应用层序地层学原理及南堡凹陷沉积充填背景研究,认为柳南次凹的沉积体系类型为冲积扇、扇三角洲、水下扇、重力流及湖泊沉积体系。冲积扇及水下扇体系在低位体系域中发育,高位体系域中扇三角洲体系和重力流发育,湖扩体系域中湖泊体系非常发育。

| Abstract: | Based on comprehensive analysis of high resolution 3D seismic,well and lots of geological data and characteristics of sequences boundaries,Dongying Formation could be divided into 1 first-order sequence,2 second-order sequences and 4 third-order sequences.Then sequence composition is analyzed and the system tracts are identified,finally the regional third-order sequence model is established.According to sequence framework analysis,we find that master control factors are tectonism,provenance and lacustrine w... |
