摘　　要：安徽省沿江地区属中低温地热分布区,地热分布与构造关系密切,热储层多是基岩裂隙、岩溶地层,铜陵市位于长江南岸,本文以铜陵市朱村区域为研究对象,结合地质勘探成果,通过对该区域地热地质及水文地质特征进行分析,结果表明:该区域地下水呈现明显活动迹象,具有形成"层状热储"的地质背景,可确认地热类型为层状,热储层为三叠系中下统南陵湖组和东马鞍山组厚层~薄层灰岩,深度1 500 m,水温48℃左右。具有较好的开发利用价值。研究结果为合理开发区域地热资源提供依据。The area of low-temperature geothermal distribution along the Yangtze River in Anhui Province is closely related to geothermal distribution and tectonics. The thermal reservoirs are mostly bedrock fissures and karst formations. Tongling is located on the south bank of the Yangtze River. This study is based on Zhucun,Tongling,and combines geological exploration results. Through analysis of geothermal geology and hydrogeological characteristics in the region. The results show that the groundwater in this area shows obvious signs of activity and has the geological background of formation of ＂ stratiform thermal storage＂. The geothermal type can be confirmed as stratiform. The thermal reservoir is a thick layer to thin layer limestone of the middle and lower Triassic Nanling lake group and the East Ma＇anshan formation,with a depth of 1500 m,and the water temperature is 48 degrees centigrade to the left right,and has a good value for exploitation and utilization. The results provide a basis for rational development of regional geothermal resources.
