本文对西湖凹陷保俶斜坡历年来不同工区的化探资料，重新进行连片研究。本文主要探讨了整个化探研究方法，并将整个保俶斜坡地区作为一个地球化学背景场进行资料处理，以此了解地球化学异常在斜坡上的分布情况。建立了化探异常模式，分析了化探异常的分布特征，为今后的勘探开发提供依据。 In this paper, the geochemical exploration data of different workplaces of Baodi slope over the years in Xihu Sag have been reconnected. This paper mainly explores the research methods of geochemical exploration, and treats the entire Po Slope area as a geochemical background field for data processing to understand the distribution of geochemical anomalies on slopes. The geochemical anomaly model has been established, and the distribution characteristics of geochemical anomalies have been analyzed, providing the basis for future exploration and development.
