APPLICATION OF COMPREHENSIVE GEOPHYSICAL METHODS IN HYDROGEOLOGICAL EXPLORATION: A Case Study of Zhejiang Industrial Park in Dongning City

To meet the urgent need of potential water sources for the Zhejiang Industrial Park in Dongning City, on the basis of observation and study of existing wells, the methods of high density resistivity and induced polarization are combined to establish a geophysical model for water resources exploration. With further prospecting in related areas, combining the hydrogeological data and well completion conditions to delineate well locations, the success rate of drilling is up to 100% by verification. Analysis on the actual application effect of multiple geophysical methods in the area shows that the combination of high density resistivity and induced polarization methods can improve the accuracy of water exploration and well completion in groundwater prospecting application with similar hydrogeological conditions.
