Abstract

Groundwater is an essential source of drinking water in water-deficient regions. The authors mainly discussed the groundwater exploration of a wind power station in granite mountainous area, and integrated geophysical methods (i.e. vertical resistivity electrical sounding method with a three-electrode configuration and frequency selection method of natural electric field) were used to carry out in-site exploration work. Firstly, the authors carried out three-electrode resistivity sounding profile work, and studied 2D finite element inversion. The 2D resistivity distribution characteristics and the favorable well position of sounding profiles had been obtained. On the basis of the resistivity sounding work, the frequency selection method of natural electric field (FSMNEF) was further developed on the original geophysical profiles. The precise position of the well was determined by the small volume effect of FSMNEF, and the sounding of FSMNEF was used at this position to determine the depth of the abnormal body. Subsequent drilling results validate the effectiveness of geophysical methods, the resistivity anomaly of geo-electrical cross-sections of three-electrode sounding is very intuitive, and FSMNEF has high accuracy in horizontal positioning and depth judgment of the aquifer, and is convenient for construction. The application results show that FSMNEF is an efficient, cost-effective tool for groundwater exploration, the field crews are small, and it has been extremely useful when coordinated with background hydrogeology or other geophysical methods.
