Application of comprehensive geophysical prospecting to groundwater exploration in Ritu County of the Ali area
摘要
Abstract
Surface water resources are scarce in Ritu County of the Ali area due to the absence of large rivers.The strata in the area are primarily composed of Jurassic and Cretaceous sedimentary rocks,exhibiting significantly varying spatial water abundance,thus posing challenges in water exploration through drilling.Based on hydrogeological survey data,this study summarized the occurrence patterns of pore water in Quaternary unconsolidated rocks and fissure water in fault structures and the electrical characteristics of aquifers in the ar-ea.It explored the structural fissure water with high water abundance in the area using the high-density resistivity method and the audio magnetotelluric method.Based on the geophysical exploration results,it delineated favorable aquifers.Furthermore,it verified the ex-ploration accuracy through drilling,obtaining high-yield water wells,and ensuring the supply of drinking water.Therefore,the combi-nation of multiple geophysical exploration methods is effective in groundwater resource surveys,improving the exploration accuracy of groundwater resources and providing effective technical support for well deployment.关键词
