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。

The Baochu slope had been divided into several study areas including Yingcuixuan,Pingbei, Pingnan and Pingzhong. In every study area, the geochemical prospecting has been developed in recent years. So many geochemical data was provided form these study areas. But every study area has its respective geochemical background. Ih this study, we summed up all of the data in the past and linked the four study areas into one. It is said that the Baochu slope is regarded as one geochemial background.on this basis, the geochemical data was processed, and the geochemical abnormal distribution was determined. We also set up the geochemical abnormal model, and analysed the feature of the geochemial abnormal distribution, which will provide the basis for the oil/gas exploration and development in the future.
