摘要: 在自然界,高氟、高砷、高矿化度劣质地下水(简称"三高地下水")一般多为伴生关系,且多赋存于以黏土、亚黏土等细颗粒为主的沉积岩地层中,细颗粒岩性及高矿化度地下水表现为低电阻率的地球物理特征。因此,通过圈定低电阻率值的分布范围划分出细颗粒岩性地层与高矿化度地下水的分布范围,从而达到在劣质地下水区中圈定出可饮用地下水分布范围的目的。文中通过对地层电阻率、地下水电阻率与地下水孔隙度、地下水矿化度之间数学关系的研究,建立了以高分辨率电法为主的在劣质地下水区勘查可饮用地下水的地球物理勘查模式,并在新疆等地进行了应用,取得了较好的效果,为在劣质地下水区勘查可饮用地下水提供了一种新的技术思路。

Abstract: In nature,poor quality groundwater of high fluorine,high arsenic,and high salinity(referred to as the"three highs water"),is always associated with each other,and exists in fine-grained sedimentary formations such as clay,loam and etc.The fine grained soil and high salinity groundwater are featured with low resistivity.So,by delineation of low resistivity areas,the distribution of fine-grained rock formations and high salinity groundwater can be mapped,thus to achieve the goal of mapping potable water in large particle stratum in poor quality groundwater region.In this paper,through the research of the mathematical relationship of the stratum resistivity,groundwater resistivity and groundwater porosity,and groundwater salinity,the geophysical prospecting model of potable groundwater in poor quality groundwater region based on high resolution resistivity method was established.We applied this model to several areas in Xinjiang Uygur Autonomous Region and achieved approving effects.The geophysical model offers a new technological concept for poor quality groundwater prospecting.

Key words: poor quality groundwater region, geophysical prospecting theory and application, application effect
