运用Petrosys盆地模拟系统,定量和动态地模拟了珠江口盆地三个主要坳陷的沉降过程,论述了沉降速率的变化与生储盖发育之间的关联,认为珠江口盆地构造沉降史具有幕式、多阶段变化的特征。盆地第一幕和第二幕沉降是盆地发育的主要时期,奠定了盆地的构造格架。形成了盆地主要的沉积地层和油气资源。第三幕沉降为盆地的改造和完成阶段,是盆地区域盖层发育的主要时期。
The Petrosys basin simulation system was used to quantitatively and dynamically simulate the sedimentation process in the three major depressions in the Pearl River Mouth Basin. The correlation between the sedimentation rate and the evolution of the genesis and cover was discussed. It is concluded that there is an episode of tectonic subsidence in the Pearl River Mouth Basin , Multi-stage changes in the characteristics. The first and second submerged subsidences of the basin are the main periods of basin development and have laid the tectonic framework of the basin. The basin formed the main sedimentary formations and oil and gas resources. The third act of subsidence is the transformation and completion stage of the basin, which is the main period for the development of the caprock in the basin.
