旋回层序地层学研究及应用
|
摘要
层序地层学是研究地层分布的一门学科 ,它是在地震地层学的基础的上综合了所有地层学的最新发展而诞生的 ,是地质学、地球物理学和计算机技术相结合的产物。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。文章介绍了T .A .Cross领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 ,并以此为指导 ,利用钻井、地震资料、岩心和各种分析资料 ,对某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
With the development of the principle and approach of sequence stratigraphy it could be used in all types of strata including marine,non marine and mixed marine/non marine strata.The enhancement of stratigraphic correlation results that sequence stratigraphy can contribute directly to all stages of the exploration and development. Based on the principle of cycle sequence stratigraphy,this article gives the sequence stratigraphy framework and reservoir prediction of Paleogene in studying area,using drilling well,seismic data,core and other data. According to logs data of the region,20 short term base level cycles(SSC)and 6 mediate term base level cycles(MSC)could be identified in studying region.There are three types of SSC:low accommodation,middle accommodation and high accommodation and three types of MSC:progradation retrogradation symmetric,progradation retrogradation asymmetric and progradation retrogradation extreme asymmetric cycles in these cycles.
