摘要(Abstract)：

渤中21-22构造区构造活动活跃、断裂系统复杂。利用地震、钻井、地化和试油等资料,研究渤中21-22构造区断裂分布、断裂演化等特征,分析断裂系统对油气成藏条件的控制作用。结果表明:古近纪早期强烈伸展作用控制渤中西南次洼的形成,进而控制烃源岩的分布;在印支晚期、燕山早期、燕山中期和燕山晚期叠加作用控制下,研究区发育构造圈闭、岩性—构造圈闭、岩性—地层型圈闭等类型;印支晚期、燕山早期和燕山晚期等构造运动控制古生界碳酸盐岩储层物性;由断裂、不整合面和砂(砾)岩层等共同组成研究区的疏导体系,其中断裂占主导地位。已钻井揭示研究区为油气有利的优势聚集区,具有较大的勘探潜力。
