摘要
以潍坊应急水源地东小营富水区为例,在充分了解研究区水文地质及地球物理特征的基础上,分别对高密度电阻率法和水文测井的原理、工作方法及应用效果进行综合分析,解释推断研究区含水层结构特征,建立水文地质参数测井解释模型,对含水层的矿化度、渗透系数及单位涌水量等参数进行估算。结果表明,物探解释成果与抽水试验及水质分析结果吻合度较高。研究认为,综合物探方法在水文地质特征分析中具有较好的适用性,可为应急水源地调查评价提供技术支撑。
Taking Dongxiaoying water-rich area of Weifang emergency water sources as an example,on the basis of fully understanding the hydrogeological and geophysical characteristics of it,this paper comprehensively analyzed the principles,working methods and application effects of high-density resistivity method and hydrological logging,interpreted the structural characteristics of aquifers in the study area,and established hydrogeological parameters Logging interpretation model to estimate the salinity,permeability coefficient and per unit of water inflow.The results show that the geophysical interpretation are in good agreement with those of pumping test and water quality analysis.It is concluded that the comprehensive geophysical prospecting method has good applicability in the analysis of hydrogeological characteristics and can provide technical support for the investigation and evaluation of emergency water sources.
