Abstract: The basin at the mouth of Pearl River is a large sedimentary basin primarily of Tertiary origin, having undergone three stages of evolution: from late Cretaceous to early Oligocene, from middle Oligocene to early Miocene and from middle Miocene to Quarternary. The basic structural patterns formed in the basin include three types of depression and two types of uplift, either of fluviolacustrine, or of semi-closed sea, or of open sea deposition. They have plentiful oil source, good reservoir properties and excellent capping and trapping conditions very well associated. All this suggests that the basin at the mouth of Pearl River is provided with the basic structural conditions to form a large oil and gas basin with great potentialities.

摘要： 珠江口盆地是一个大型新生代为主的沉积盆地,它经历了晚白垩世至早渐新世、中渐新世至早中新世、中中新世至第四纪三个演化阶段。以及由此而形成的基本构造模式——三种拗陷和两种隆起;基本沉积模式——河湖、半封闭海、开阔海三种沉积体系;有良好的生油、储油、盖层和圈闭条件及其相互配合关系。因此,珠江口盆地具备了一个大型含油气盆地的基本地质构造条件,有很大的油、气潜力。
