| 摘 要： | 中国西部大型干旱盆地盐湖中，承压卤水含水层因其中所赋存的固--液相钾矿资源储量大而成为主要含矿层。采用地面核磁共振与水文地质钻探相结合的技术方法对柴达木盆地某盐湖进行的承压卤水可采性试验，获取了含水层的相关物理参数，并将其解译为相关的水文地质参数。通过水文地质综合判断，确定了含水率 5. 4% 的富水地段。水文地质钻探验证获取了稳定丰富的涌水量，并使之成为采卤量 1. 5 ×104m3/d、KCl 含量 1. 67% 的工业性开采水源地。结果表明，核磁共振与水文地质钻探联合技术是确定盐湖晶间卤水层富水性的可靠右有效的方法。

| Abstract: | Confined brine aquifer was the main ore-beating bed in the large arid basins salt lake of western China because of its large amount of solid-liquid phase potassum mineral deposition. The combined technology of surface nuclear magnetic resonance and hydrogeology drilling verification was first used in the confined brine work- ability test of a salt lake of Qaidam Basin in China. The related physical parameters of aquifer were obtained and then interpreted as hydrogeological parameters. The water abundant areas of moisture content 5.4% were deter- mined by the hydrogeological comprehensive judgment, and the stable rich water yield was obtained by hydrogeolog- ical drillings. And make it into the industrial mining water area of 1.5 × 10^4m^3/d in brine quantity and 1.67% in KCl content. This technology tested by practice was an reliable and effective method in detecting the water abundance of salt lake intercrystalline brine aquifer and exploiting of brine resources. |
