摘要
保俶斜坡带位于西湖凹陷的西部,新生代沉积厚度可达1万m,始新统和渐新统是主要的含油气目的层段。现已发现的含油气圈闭类型不仅受构造因素控制,而且受沉积环境因素控制,预测还有与岩浆作用有关的圈闭类型。
Baoshu slope zone is located in the west of Xihu sag. Cenozoic sedimentary thickness is some thousands to 10000 metres. The layer bearing oil and gas is mainly in Eocene and Oilgo-cene. It had been found that the petroliferous trap types not noly are controlled by structural factor, but also by sedimentary cnviroment factor. The trap types controlled vocanic action are predicted.
