电阻率法在鄂北丘陵山区水文地质调查中的应用研究

The Application of Resistivity Method in Hydrogeology of North Hubei Hilly Area

摘要: 本文以鄂北丘陵山区南部皂市镇幅水文地质调查为例，在鄂北丘陵山区的物探找水实践中，综合运用对称四极电测深法、高密度电法、激电测深、电阻率测井法进行地下水勘查研究。通过四种方法的组合应用，有效避免了单一勘探方法的多解性，提高了勘探的准度与精度，最终探索出电阻率法在地下水勘查工作中“面上控制，线上定性，点上量化，井中验证”的优化模式，可较准确的划分富水区，大大提高了成井率，为鄂北丘陵山区严重缺水地区地下水勘查提供借鉴或参考意见。

Abstract: Taking the hydrogeological survey of Zaoshi town in the south of the hills and mountains of North Hubei as an example, in the practice of geophysical prospecting for water in the hills and mountains of North Hubei, this paper comprehensively uses the symmetrical quadrupole electric sounding method, high density electric sounding method, induced electric sounding method and resistivity logging method to explore the groundwater. Through the combination of the four methods applied, effectively avoid the uncertainty of single exploration methods, improve the accuracy and precision of the exploration, finally explores the resistivity method in groundwater exploration work “control, online qualitative and quantitative point, borehole verification” optimization model, can be accurately dividing the rich water, greatly improving the rate of supplying, groundwater exploration for severe water shortages in north ordos hilly mountain areas to provide the reference or reference opinions.
