摘要

水进、水退控制的进积、退积以及加积等充填样式和它们在空间上的叠置方式

是断陷湖盆层序划分的主要依据。因此

幕式构造沉降作用引起的沉积基面变化是控制层序发育及其基本特征的根本原因

沉积物供给和气候变化只是层序形成的外部条件。运用上述方法可将高尚堡油田沙河街组三段二、三亚段划分为9个副层序组和若干个副层序

极大地提高了地层划分和对比的精度。

Abstract

The progradation

retrogradation

aggradation and their superimposition patterns are the main evidence for sequence classification of fault depressed lake basin The changes in base level caused by episodic subsidence is the basic cause in controlling the developmnent and property of sequences

the source supplementation and climate changes is the external condition of the sequences According to the mentioned above

the reservoirs of 2-3rd submembers of the third member of the Shahejie Formation in Gaoshangpu Oilfields could be divided into 9 subsequence groups and several subsequences This could considerably improve the accuracy of stratigraphic classification and correlation
