摘要(Abstract)：

莱北低凸起构造样式和构造演化控制围区油气成藏和古近系砂体展布。结合最新的三维地震资料,根据断裂体系特征、构造样式和地层厚度等,研究莱北低凸起构造演化特征,在走滑构造作用下解析沙河街组和东营组古沟谷构造样式对沉积体系的控制作用。结果表明:新生代早期伸展作用控制莱北低凸起的初始隆升,始新世时期郯庐走滑断裂带活动强度加剧,剪切应力引起凸起发生扭动旋转,诱导先存边界断层发生共轭走滑;旋转运动使莱北低凸起北西侧和南东侧远离主走滑断层,造成局部伸展沉降,北东侧和南西侧发生挤压汇聚,产生垂向或水平方向调节构造,形成莱北低凸起现今的构造格局。莱北低凸起北西侧的快速沉降,引起郯庐断裂中支走滑断裂形成的古沟谷也逐渐向沉积坡折带转化,扩大东营组辫状河三角洲沉积体系的规模。该研究结果为莱北低凸起寻找有利储集层发育区提供指导。

关键词(KeyWords)：莱北低凸起;构造演化;共轭走滑断层;块体旋转;沉积坡折带
