摘　　要：渤海湾盆地黄骅坳陷新构造运动强烈,影响新近纪以来油气类型和分布。基于新的7.654×10~3 km^2高精度三维地震及钻井资料,研究新近纪以来新构造运动特征及其与油气活动的相关性。结果表明:黄骅坳陷新构造运动经历明化镇组早期张扭断陷和明化镇组中晚期-第四纪差异升降两大演化阶段,形成晚期断裂、火山活动和角度不整合面三大地质特征,对油气成藏的控制作用表现在四个方面,即控制浅层圈闭的形成与分布、促进古近系源岩演化、为油气运移提供输导通道、调整并控制油气晚期动态成藏。黄骅坳陷歧口地区新近纪帚状断裂发育带勘探潜力较大,是寻找中浅层规模储量的有利区带。Neotectonism in Huanghua Depression of the Bohai Bay Basin is strong,which affects the types and distribution of hydrocarbon since Neogene.Characteristics of neotectonic movement and their effect upon hydrocarbon accumulations were analyzed based on 7.654×10~3 square kilometers high resolution 3 Dseismic and drilling data.The results show that neotectonism in Huanghua Depression shows two evolutionary stages,including tense-shearing fault depression stage in early Minghuazhen Formation and differential uplift stage in late Minghuazhen-Quaternary.Neotectonism plays an important role in formation of late faults,volcanic activity and unconformities.The control of hydrocarbon accumulation is mainly reflected in four aspects.First,controlling the formation and distribution of shallow traps;second,promoting the evolution of Paleogene source rocks;third,providing pathway for oil and gas migration;fourth,adjusting and controlling late oil and gas dynamic accumulation.The Neogene brush fault zone in Qikou Area of Huanghua Depression has great exploration potential,which is the favorable zone for searching for the medium-shallow reservoirs.
