摘　　要：为厘清本区油气成藏差异性的主控因素,基于钻井、三维地震及地质资料对渤中34-A含油气构造区域构造、储层展布特征及相互关系进行剖析,系统性分析了断裂组合样式、断裂活动性及断砂耦合对油气分布的控制作用。首先,断裂组合样式和活动性控制圈闭演化特征;其次,断裂系统活动性与油气成藏“时-空-源”耦合控制油气运聚;断-砂耦合控制油气差异分布;最后,该认识对黄河口凹陷斜坡带及同类构造油气成藏规律和勘探部署具有指导意义。In order to analyze the regional structure,reservoir distribution characteristics and their relationships based on drilling,3D seismic and logging data in BZ34-A oilfield,the control effects of fault combination pattern,fault activity and sand coupling on oil and gas distribution are systematically analyzed.First of all,the fault combination style and the activity control trap evolution characteristics;Secondly,the activity of the fracture system and the“time-space-source”coupling of hydrocarbon accumulation control hydrocarbon migration and accumulation.Finally,the fault-sand coupling controls the hydrocarbon differential distribution.
