摘要(Abstract)：

受多期构造运动影响,渤海海域428潜山的构造演化过程相对复杂。根据新三维地震和钻井资料,采用水平相干体技术,分析428潜山的地层结构和构造特征,探讨构造成因演化及其对油气成藏的影响。结果表明:研究区潜山东、西两个构造脊分别具有古生界和前寒武系、中生界和前寒武系双层结构特征;经历印支运动期的近SN向逆冲挤压、燕山运动早期的NW向继承性挤压、燕山运动中期的NW-SE向强烈伸展断陷、燕山运动晚期的NWW向挤压隆升,以及喜山运动期以来的伸展、走滑复合叠加改造,428潜山发育长期活动、早期活动和晚期活动3类断层,一系列网格状裂缝及多个不整合面改善潜山储层物性,增强油气输导能力。该结果为渤中坳陷区域内潜山油气勘探提供参考。
