瞬变电磁法在桑科水源地水文地质勘察中的应用

Application of transient electromagnetic method for Water Sources Hydrogeological exploration in SangKe

大夏河流域地下水资源丰富,水质优良,具有很好的开发价值。为了解决工业用水问题,在水文地质勘察中需要物探工作来推测水源地第四系覆盖层厚度变化及含水层富水区位置,为后期水源地工程勘查提供依据。本文依据2处已知成井钻井资料完成1条瞬变电磁探测剖面数据采集和资料解释,并对水源地井位的选址提出了合理的建议。

Daxia river basin is rich in groundwater resources and has good water quality.In order to solve the problem of industrial sewage,geophysical exploration is needed in the hydrogeological survey to estimate the change of quaternary overburden thickness and the location of aquifer rich water area of water source area,so as to provide a basis for the later engineering exploration of water source area.In this paper,data acquisition and data interpretation of a transient electromagnetic detection profile are completed based on the drilling data of two known Wells,and reasonable Suggestions are put forward on the site selection of well location of water source..
