摘 要：
为研究贵州变质岩区地热水赋存规律,利用瓮安老坟嘴SK08-2地热井水化学组分和钻井测温资料,分别进行水-岩平衡判断和建立井深-井温回归方程,最终估算出地热水热储温度及循环深度。结果表明,瓮安老坟嘴地热水热储温度约为52℃;地热水循环深度约为1 650m;地温梯度变化在5～35.2℃/km,平均19.6℃/km。作为贵州变质岩区地热水成功开发的首例,SK08-2井地热水的研究可为今后变质岩区地热找水提供科学依据。

摘 要：
In order to research geothermal water storage rule in Laofenzui metamorphic rock area,based on water chemical components and temperature data measured from SK08-2 well,the water-rock equilibrium judgement and regression equation between well depth and well temperature are used to estimate the geothermic water temperature and circulation depths.The result shows that the geothermal water temperature is 52 ℃,the circulation depth is about 1650m,the geothermal gradient vary between 5 to 35.2 ℃/km and the average value is 19.6 ℃/km.As the first time for the successful development of geothermal water,the case study will supply scientific evidence for the research on geothermal water in metamorphic rock area.
