| 摘 要： | 珠江口盆地B凹陷的形成演化受神狐、珠琼、南海等多次构造运动控制.其基岩地层受太平洋和亚洲板块碰撞作用形成北东向浅层断褶构造带.该断褶构造带原始构造形态比较简单,但受后期多次拉张构造活动的改造,使得现今产出的裂陷构造内幕非常复杂.本文根据地震资料解释、钻井资料分析和油气勘探开发成果,详细阐述了B凹陷断层的类型、组合型式及断裂系统分布特征,包括:(1)断层主要有正、逆断层和走滑断层等类型;(2)断裂主要有羽状构造、花状构造、帚状构造和滑脱构造等组合型式;(3)根据断裂带走向,发育有8组不同走向的断裂带:北西西向、近东西向、北东东向、北西向、北东向、北北东向、北北西向、近南北向.

| Abstract: | The formation and evolution of the B depression in the Zhujiangkou basin were controlled by the tectonic movements,which are Shenghu,Zhuqiong,South Sea movements,and so on.The collision between the Pacific plate and the Asian plate resulted in the shallow NE fault and fold tectonic zone in the basement of the basin.The zone had a simple shape at early stage,but multi-stage extensional movements reformed its characteristics and made the modern structures within the zone very complex.Depending on the seismic ... |
