摘要
前人研究认为高邮凹陷联盟庄地区戴二段地层与下伏的戴一段地层不是连续过渡的,它们之间存在沉积间断,其上、下为各自不同的断裂系统。通过区域沉积特征、断层性质、砂体的可对比性以及泥岩隔层厚度渐变规律三个方面的研究,认为联盟庄地区戴二段地层与下伏的戴一段地层之间沉积是连续的,断层和构造从下至上均存在一定的连续性和继承性。
Previous researches indicated thal the strata of the first and underlying second members of Dainan Formation were discontinuous in l.ianmengzhuang area in Gaoyou Sag; there was a depositional hiatus between them,which had their own different fault system at the upper and lower. In this paper, through studies in three aspects of area sedimentary charac- teristics, fault nature and comparison of sand bodies and changing rule of thickness of mudstone interlayer, research results suggested that the strata of the frist and underlying second member of Dainan Formation were continuous,faults and struc- ture from top to bottom had continuity and inheritance.
