摘　　要：西藏自治区昌都地区芒康县盐井乡全年产盐约1 500t,除供应当地外,还远销左贡、察雅、贡觉等县及滇西地区,由于开采年代久远,大部分卤水井已枯竭,急需进一步勘探。鉴于盐井地下水具有中温、高矿化的特点,采用EH-4系统高频大地电磁测深探明深部储层的信息及含盐地下水上升的通道信息,进一步预测该区域盐矿层赋存状态,通过实例证明该方法可行的。With an annual output of about 1,500 tons of salt inMangkang county of Tibet, most of the brine has been dried up, so the further exploration of wells is urgently needed. Since the water in salt wells has the feature with the moderate temperature and high salinity, the high- frequency magnetotelluric sounding of the EH -4 system is used to obtain the information in the deep reservoir and the information of water channel, and it also predicts the storage in salt mining of this area. The method is proved to be good.
