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。
The Pearl River Mouth Basin is a large Cenozoic sedimentary basin that experienced three stages of evolution from Late Cretaceous to Early Oligocene, Middle Oligocene to Early Miocene to Middle Miocene to Quaternary. As well as the basic tectonic modes formed from them - three kinds of depressions and two types of uplifts; basic sedimentary models - three kinds of sedimentary systems of rivers and lakes, semi-enclosed sea and open sea; good oil and oil reservoirs and cap rocks And trapping conditions and their interrelationships. Therefore, the Pearl River Mouth Basin possesses the basic geological conditions of a large petroliferous basin and has great oil and gas potential.
