保俶斜坡属西湖凹陷新生代沉积的大型缓坡带，具有复杂的、独特的沉积和构造格局。本文着重论述保俶斜坡下第三系（目的层段）的地质条件，对含油气性进行了综合分析，认为已钻探区（平中、平北）为有利的油气富集区，并预测未钻探区（平南、海礁湾、迎翠轩）为潜在的含油气远景区。
Baodi slope belongs to the large Cenozoic sedimentary large gentle slope belt in Xihu Sag with complex and unique sedimentary and tectonic pattern. This paper focuses on the geological conditions of the Tertiary (target interval) under the Po Slope and conducts a comprehensive analysis of the hydrocarbon-bearing properties. It is considered that the drilled area (Pingzhong and Pingbei) is a favorable oil and gas accumulation area, and the predicted The drilling area (Pingnan, Haiwan Bay, Ying Cuixuan) is a potential oil and gas prospect.
