鄂北部为丘陵地貌,主要地层有下元古界桐柏群、中元古界红安群、上元古界随县群及震旦系片岩、片麻岩等变质岩,白垩系—第三系的“红层”及第四系冲洪积、残坡积松散岩类,属于贫水区,找水困难。在对孝感500KV变电站的供水水文地质勘察中,运用核磁共振直接找水,并在场区布置合理的电法勘探工作,根据勘探成果解释,确定合理井位,再钻探成井,解决了变电站的用水难题。
The northern part of Hubei Province is a hilly landform. The main strata are the Tongbai Group of the Lower Proterozoic, the Hongan Group of the Middle Proterozoic, the Shangxian Group of the Proterozoic and the metamorphic rocks of the Sinian schist and gneiss, Cretaceous-the third Department of “Red Layer ” and Quaternary alluvial plot, residual slope loose loose rock, belong to the water-poor area, find water difficult. In the water supply hydrogeological survey of Xiaogan 500KV substation, the nuclear magnetic resonance is used to directly search for water and arrange the reasonable electrical prospecting work in the field area. According to the interpretation of exploration results, the rational well location is determined and the well drilled again to solve the water problem of the substation .
