| 四川省攀枝花仁和地区地质构造复杂，地热地质研究程度较低，属于地热开发勘查空白区。基于此，为探明攀枝花仁和地区的地层发育情况及隐伏断裂特征，圈定地热资源赋存有利位置，本文采用(音频)大地电磁测深法(AMT/MT)及后期钻孔验证等研究手段，探查研究区地下电性结构、地层发育状况及断裂位置、埋深等情况。综合分析可知研究区内奥陶系汤池组、红石崖组致密砂岩、石英砂岩为盖层，下伏巧家组白云岩、白云质灰岩为热储层，受区域内断裂影响，深部地热水沿断裂系统向上运移。在地热赋存有利位置，设计 800 m地热勘探孔 ZK01，后期完钻深度 810 m，出水量最大可达 496.9 m3/d，井口出水温度为 |

| The geological structure of Renhe District in Panzhihua, Sichuan Province is complex, and the re-search level of geothermal geology is relatively low, which belongs to the blank area of geothermal development andexploration. Based on this, in order to explore the geological development and hidden fault characteristics in theRenhe District of Panzhihua, and delineate favorable locations for geothermal resources, this paper uses researchmethods such as (audio) magnetotelluric sounding (AMT/MT), and later drilling verification to basically investigatethe underground electrical structure. The research area has preliminarily identified the underground electrical struc-ture, geological development status, fault location, burial depth, and other related information. Comprehensive analy-sis indicates that within this area, the Ordovician Tangchi Formation and Hongshiya Formation consist of tight sand-stone and quartz sandstone acting as caprocks, underlain by the Qiaojia Formation dolomite and dolomitic limestoneserving as the geothermal reservoir. Deep geothermal water migrates upward along fault systems influenced by re-gional tectonic structures. At a favorable location for geothermal occurrence, a geothermal exploration borehole(ZK01) was drilled to a planned depth of 800 m. The final completed depth reached 810 m, with a maximum dis-charge rate of 496.9 m3/d and a wellhead water temperature of 30.2 ℃. The successful exploration of geothermal wa-ter in the previously unexplored geothermal zone of Renhe District, Panzhihua, holds certain social value. |
