摘要(Abstract)：

基于三维地震资料解释和构造几何学,研究南堡凹陷3号构造中—深层两期断裂的油藏的控制作用。结果表明:南堡凹陷3号构造中—深层具有构造体系转换界面和构造反转界面,沙河街组顶部是构造体系转换的关键界面,早期以北东向伸展为主,晚期以南北向伸展兼右旋走滑为主;南堡凹陷3号构造主断层具有长期发育、旋回式活动特征,东西向断层具有活动时间晚、强度稳定特征,存在3类区域构造样式和12类局部构造样式;沙河街组一期断裂影响程度较小,造成深部断层具有较好的断层封闭性,而东营组二期断裂向下断入沙河街组一段内且与砂体连通,在伸展期极易开启并造成油气沿着浅部断层向上运移,深部油气聚集成藏非常有利,也为油藏聚集的有利场所。
