摘　　要：本文从地质概况、地热水的成因、热储构造、补径排条件及热显示特征等方面分析研究了重庆市彭水县郁山镇的地热地质特征。研究结果表明:彭水县郁山镇地热水的形成主要以大气降水为补给源,以地温梯度及化学热等方式增温,以郁山断裂带的断层裂隙通道、岩溶通道作为水及热的传递通道,顺层作纵向径流,在地表减压地段或以人工钻井揭露方式排出地表形成地热水。彭水县郁山镇地热地质条件较为优越,其周边热显示较明显,通过钻井揭露,在合适的深度,如2000 m左右可获取较理想的地热水,开发利用前景较好,可促进郁山镇旅游业的发展。This paper analyzes and studies the geothermal geological characteristics of Yushan Town,Pengshui County,Chongqing from the aspects of geological overview,genesis of geothermal water,heat storage structure,geothermal water supply,runoff,discharge conditions and heat display characteristics.The results show that the formation of geothermal water in Yushan Town,Pengshui County mainly takes atmospheric precipitation as the supply source,increases the temperature by means of geothermal gradient and chemical heat,takes the fault fracture channel and karst channel of Yushan fault zone as the transmission channel of water and heat,makes longitudinal runoff along the stratum,and discharges the geothermal water from the surface in the area of surface decompression or by manual drilling.The geothermal geological conditions in Yushan Town,Pengshui County are superior,and the surrounding heat display is obvious.Through drilling exposure,ideal geothermal water can be obtained at an appropriate depth,such as about 2000 m.The prospect of development and utilization is good,which can promote the development of tourism in Yushan Town.
