摘要
根据构造演化剖面的分析结果,确定了高邮凹陷南部断阶带。随着三垛运动的结束,南断阶构造活动趋于平静,各断层在盐城期相继停止活动,形成了现今的构造格局。断裂的活动时期与油气运移时期良好匹配,断层成为油气垂向运移的主要通道,并在平面上相互切割形成有利的油气圈闭。
The south terrace in Gaoyou sag is presented, according to the analysis of the structural evolution section. That is, when the Sanduo movement ended, the south terrance activity tended towards calming down, and all faults in it stopped acting, accordingly, hence forming present structural framework. Once shaping a good match between the fault-active period and hydrocarbon-migrating period, could the faults become major channels for vertical migration of hydrocarbons and lateral crosscutting followed by forming favorable hydrocarbon traps in Gaoyou sag.
