摘要
通过鄂尔多斯盆地东部黄土覆盖区试验实例,介绍了地面核磁共振找水技术的发展现状及其基本原理、测量参数、影响因素、技术特点和应用范围,说明了该方法在探测碎屑岩类浅层风化裂隙水和构造带裂隙水中的效果。同其它物探方法相比,该方法可量化含水层深度、厚度、单位体积含水量以及平均孔隙度等水文地质参数,在地下水勘查中具有广阔的应用前景。
To take a case study in loess covering area in eastern Ordos Basin as an example, introduced status quo of surface NMR technique used in water research and its basic principle, measuring parameters, influencing factors, technical features and range of application. Also illustrated results of the technique used in clastic rock shallow weathered zone fissure water and structural belt fissure water researches. As compared with other geophysical prospecting methods, this method can quantizing hydrogeological parameters of aquifer depth, thickness, volumetric water-beating capacity and average porosity, thus make it capacious application prospect.
