摘　　要：青海茶卡盆地(漠河农场一带)山前倾斜平原中、后缘地带主要含水层厚、分布范围广且稳定连续均匀,但水位埋藏深,加之近年高山雪线上移,蒸发量增大,冬春干旱,致使地下水资源量减少。为高效、经济在该区解决用水问题,采用五极纵轴测深法在该区进行探测,并指导钻探工作。探测结果表明,五极纵轴测深在一定地电条件下,对地层结构具有高分辨率、解释简单、直观、准确及经济等特点,在第四系似层状地层找水中也能取得好的效果,对钻探成井可发挥行之有效的指导作用。The main aquifers in the middle and back edge of the Piedmont inclined plain in Chaka basin(Mohe farm area)are thick,stable,continuous and even,but the water level is buried deep.In addition,in recent years,the mountain snow line has moved up,the evaporation capacity has increased,and the drought in winter and spring has reduced the groundwater resources.In order to solve the problem of water consumption in this area efficiently and economically,the five-pole electrical sounding method is used to detect the area and guide the drilling work.The detection results show that under certain geoelectric conditions,the five-pole electrical sounding has the characteristics of strong resolution,simple interpretation,intuitive,accurate and economic,etc.it can also achieve good results in water exploration in Quaternary stratiform strata,and can play an effective guiding role in drilling well completion.
