摘　　要：为开发利用镇江大路圌山地区地热资源,在分析该区深部碳酸盐岩分布及岩溶发育规律等基础上,采用CSAMT方法,结合重力、航磁等地质解释,对区内储盖结构、隐伏断裂破碎带等进行分析推断,设计了1口地热井。经钻探验证,水温、水量等各项地热井指标均达到了预期,实现了火山岩覆盖区深部岩溶型地热勘查的突破,对类似地区勘查开发该类型地热资源具有指导意义。Chui Mountain area is located in Dalu Town,Zhenjiang.To develop its geothermal resources,based on the analysis of the distribution of deep carbonate rocks and the law of karst development,a geothermal well is designed by using the CSAMT method and the geological interpretation such as gravity aeromagnetic,to analyze and infer the reservoir cap structure and the hidden fracture zone in the exploration area.Drilling verification show that all geothermal well indexes such as water temperature and water quantity have reached the expectations,which has achieved a breakthrough in deep karst geothermal exploration in volcanic covered areas,and has guiding significance for the exploration and development of this type of geothermal resources in similar areas.
