摘要
沉降史分析目前已成为盆地分析中的重要技术。本文以东营凹陷为例 ,从层序分析入手 ,建立了该凹陷的等时地层格架。在此基础上 ,利用 EBM盆地模拟系统 ,对凹陷的沉降史进行分析。通过典型剖面的回剥 ,对剖面上不同部位的沉降作出比较 ,进而反映该凹陷的沉降特征 ,总结了该凹陷的构造发育与充填演化及其对油气生成、运移的控制关系 。
Subsidence history analysis becomes an important technology now in basin analysis. Taking Dongying Depression for an examlpe, the paper started from analyzing stratigraphic sequence, created isochronic stratigraphic framework for Dongying Depression and analyzed subsidence history of the Depression using EBM basin modeling system on the basis of isochronic framework. The subsidence in different parts of section can be compared through back stripping a typical section and then the subsidence feature of Dongying Depression has been reflected. Studying structural development and filling evaluation of the Depression and its relations with controlling genesis of hydrocarbon and his migration can provide reliable basis for oil and gas exploration.
