| 摘 要： | 以青海省共和县地下热水为研究对象,对所取得的水样进行水化学以及氢氧同位素测试,并分析测试结果。结果表明：共和地区地下热水水化学类型以Cl-Na型为主;地下热水受到浅表层氧化作用的影响较大,所处环境的封闭性较差,有浅层地下水或地表水的混合;地下热水受大气降雨补给;地下热水热源和水源不是同一来源;地下热水未达到水岩平衡状态,估算出地下热水热储温度在37.59~108.22 ℃之间,循环深度为500~2000 m,属于中低温地热系统。

| Abstract: | Taking the geothermal water in Gonghe basin of Qinghai Province as the research object, the water samples were tested for the hydrochemistry and hydrogen and oxygen isotope, and the results were analyzed. The analysis results show that the main hydrochemical type of geothermal water in Gonghe area is Cl-Na type. Geothermal water is greatly affected by the superficial oxidation of shallow surface layer, and the sealing of the environment is poor. Geothermal water is supplied by rain. The geothermal heat source and water source are not the same. Geothermal water does not reach the chemical equilibrium state of water- rock reaction, The reservoir temperature of geothermal water is estimated to be the range of 37.59-108.22 ℃. The circulation depth of geothermal system is 500-2000 m, which belongs to the medium temperature geothermal system. |
