层序地层学是研究地层分布的一门学科,高分辨率层序地层学是当今层序地层学发展的主要方向之一。本文将介绍T．A．Cross倡导的成因地层组提出一种高分辨率层序地层分析方法——旋回层序地层学,探讨其关键技术运用方法,并以此为指导,利用钻井、地震资料、岩心和各种分析资料,对渤南凸起地区的层序进行了综合分析研究,建立了下第三系层序地层格架。
Sequence stratigraphy is a discipline to study the stratigraphic distribution. High-resolution sequence stratigraphy is one of the main directions in the development of sequence stratigraphy. This article will introduce T A. The formation stratigraphy group initiated by Cross proposed a high-resolution sequence stratigraphic analysis method - cycle sequence stratigraphy, and explored the application of its key technologies. Using this as a guide, drilling, seismic data, cores and various analytical data , A comprehensive analysis of the sequence of the Bonan raised area has been made and the framework of the Lower Tertiary sequence stratigraphy has been established.
