摘　　要：西安市临潼区雨金镇辖区地下水普遍存在“苦咸水”问题,区内地下潜水与浅-中层承压水多项水质参数超标;据调查井资料,深层承压水富水性与水质较好而开发利用程度较低,亦为本次勘查工作的主要取水层段。在研究现阶段区域水文地质成果的基础上,依次进行水文地质调查、电测深、施工探采结合井、测井、分层抽水试验与钻探施工成井等工作,同时进行物探与水质的专项分析。通过本次综合勘查,基本查明了区内的地层特征、地下水赋存、运移规律及不同含水层段的水质特征。钻探验证了在该区施工水源井取深层弱微咸水是可行的。Groundwater in the area under jurisdiction of Yujin Township,Lintong District,Xi’an City generally has bitter brackish water issue.Multiple water quality parameters are overproof in the area’s phreatic water and shallow to medium deep confined water.Based on well investigated data,water yield property and water quality are better,but degrees of exploitation and utilization lower,and deep confined water is the main water intake segment of this exploration target.On the basis of current regional hydrogeological studied results have carried out hydrogeological investigation,electric sounding,exploration and mining combination well drilling,well logging,layered pumping tests and drilling completion works in turn,meanwhile,carried out geophysical prospecting and water quality special analysis.Through this integrated exploration has basically identified stratigraphic features,groundwater hosting,migration patterns and water quality features of different aquifer segments in the area.Drilling data has validated that to construct water supply well intake deep brackish water is feasible.
