综合物探方法在水文地质勘查中的应用——以东宁市浙江工业园勘查为例

摘要

针对东宁市浙江工业园急需查找后备水源地的现状,利用高密度电阻率法与激发极化法组合,在对已知井观测研究基础上,建立勘查区地球物理找水模型.进一步对相关区域勘查,结合水文地质资料和成井条件圈定井位,经钻井施工验证,成井率100％.通过多种物探方法在该地区应用的实际效果分析,高密度电阻率法与激发极化法组合模式在区域相似的水文地质条件下,在地下水勘查的应用中能提高其找水和成井的准确性.%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.
