| 摘 要： | 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。

| Abstract: | Using Petrosys basin modelling system, the writers simulate quantitatively the subsidence history of three main depressions in Pearl River Mouth Basin, then discuss the relating of subsidence rate and development of source rock, reservoirs and cover rock. The result shows the subsidence history of Pearl River Mouth Basin has the dynamic character of episodic and mullstage evolution. The first and second episodic subsidence are the primary phases of Pearl River Mouth Basin evolution, which establish the structure pattern and form the dominating sediment and oil and gas resources. Under the third episodic subsidence operating, Basin finish rebuilding and shaping the configuration, |
