摘要
邵家洼陷区是济阳坳陷沾化凹陷中的一个箕状断陷。邵家洼陷区断层平面组合特征复杂,剖面组合类型多样,导致了该洼陷区断层体系的复杂性和构造类型的多样性。基底断层的活动对邵家洼陷区的沉积充填和构造格局起着重要的控制作用,它影响着油气运移的指向、路径、效率和聚集部位,主要使烃源岩层与储集层相连通而有利于油气的垂向运移。盖层断层的活动主要影响该洼陷区圈闭的形成和类型,形成众多断块或断鼻构造而有利于油气成藏。
Shaojia subsag area is a half-graben in Zhanhua sag, Jiyang depression, where complex fault systems and diverse structure types may result from complexity in lateral fault assemblages and diversification in vertical fault assemblages. The activity of basement faults has an important control on sedimentary filling and tectonic framework in Shaojia subsag, and may influence hydrocarbon migration direction, pathway, efficiency and hydrocarbon accumulation position. This activity is favourable to vertical hydrocarbon migration by making communication between source rocks and reservoirs. For the cover faults, their activity could control trap formation and types and result in a lot of fault blocks and faulted noses in favor of hydrocarbon accumulation in Shaojia subsag.
