摘要

根据地震及钻井、测井资料,编制苏北盆地高邮凹陷许庄构造断裂平面及剖面图,分析江苏油田苏北盆地许庄构造的断层特征、构造演化及其断层活动特点.结果表明:许庄构造为平行式阶梯状和"y"型断层组合,真①断层与真②断层间所夹持的断块发育多米诺式正断层.断层演化顺序为真①断层在泰州组—阜宁组沉积时,沿先期存在的逆断层回滑首先发育,并伴生次级断层,戴南组—三垛组沉积时停止活动,盐城组又有所活动;真②断层在戴南组沉积时开始发育,部分延续了真①断层伴生的次级断层,其活动持续到盐城组沉积.
Based on seismic data and well drilling and logging data,through drawing up structural maps and cross sections of Subei basin,fault characteristics,tectonic evolution and fault active characteristics of Xuzhuang segment of the southern fault zone in Gaoyou depression have been analyzed.Fault combination type of the Xuzhuang segment is parallel and ladder-like and parallel and "y" type.The fault sheets between Zhen-①fault and Zhen-②developed domino-type normal faults.Fault evolution sequence is that,the Zhen-①fault first developed along the pre-existing reverse fault slipping back in the sedimentary period of Taizhou formation and Funing formation,then,the associated secondary faults of the Zhen-①fault developed,and then,the Zhen-②fault began to develop in the sedimentary period of Dainan formation.The Zhen-①fault stopped its activities in the sedimentary period of Dainan formation,and there are minor activities in the sedimentary period of Yancheng formation.The activities of the Zhen-②fault continued until the sedimentary period of Yancheng formation.Complex fault evolution of Xuzhuang segment developed into multiple fault block reservoirs.
