摘　　要：本文以桐庐县阆里村石峦坞矿区DR1地热井为例,通过对区域构造、断裂构造、地层岩性及水文地质特征等的综合分析,将地热井位置选于区域复向斜构造内,阆里背斜的东翼,F3F6 F7断裂形成的三角区内,以富水性好的灰岩与非灰岩交界断层F3作为耙区断层。经过CSAMT物探测线及后期钻孔工作验证,成功勘探出水温为34.6℃水量936m3/d的地热水。满足了构造裂隙型带状热储地热找水需要查明储水空间及富水性这两个最基本的条件,对浙江地区构造裂隙型带状热储地热找水具有一定的指示意义。Takingthe Tonglu LangLi village Shiluanwu mining area DR1 geothermal wells as an example, through a comprehensive analysis of the regional structure, fault structure, stratigraphic lithology, hydrogeological characteristics, and so on of the DR1 geothermal wells, the DR1 geothermal well locations were assessed in the regional structure. In the Langli anticline of the east wing, the F3,F6, an F7 fractures form atriangle with a water-rich limestone and non-limestone boundary fault F3 as a rake area fault. After CSAMT detection line and post-drilling work verifcation, a water temperature of 34.6℃ and quantity of 936m3/d were determined. To meet the structural fssure type zone-shaped thermal storage to be identifed, water storage space and water-richness are two of the most basic issues. This study has a certain signifcance for tectonic fssure zone-shaped thermal storage geothermal water in Zhejiang.
