中文摘要：

为了确保大庆油田二次开发及三次采油的顺利实施,重新开展了杏南地区主要油层的高分辨率层序地层划分和对比的分析和研究工作。运用高分辨率层序地层学原理对不整合面、整合面、初次湖泛面及最大湖泛面等各级界面进行识别和对比。通过对层序边界形成机理、识别方法及标志、边界类型及特征等方面的研究,结合各级层序内部结构特征,建立研究区目的层的等时地层格架。依据各级层序界面标志,研究区目的层被分为2个长期基准面旋回LSC1和LSC2;3个中期基准面旋回MSC1、MSC2及MSC3;35个短期基准面旋回。

英文摘要：

To assure the success of the the secondary development and tertiary oil recovery of the Xingnan area in Daqing oilfield,the high resolution sequence stratigraphic classification and correlationmain on the main oil layer was againly analyzed and researched.The high resolution sequence stratigraphy is used to recognize and contrast unconformity surface,the conformity surface,the first flooding surface and maximum flooding surface etc.the all levels interface.By the research to the preface boundary formation mechanism and identifying method and marking,boundarytype and characteristic etc,combining the internal structure characteristics of all levels sequence,isochronal stratum framework of the research area stratum purpose layer is established.In accordance with the sequence of interface markers,the target strata of the studied area is divided into 2 long-term base-level cycles LSC1 and LSC2;3 medium-term base-level cycles MSC1,MSC2 and MSC3;35 short-term base-level cycles.
