摘　　要：以贵州北部遵义新蒲地区杨家湾地热井中地热水为研究对象,基于地热水的水化学组成、氢氧同位素特征,探讨了地热水的成因。研究表明,该地热水水化学类型为SO42--Ca·Mg型,有益元素主要为Sr、F。地热水的补给来源为大娄山地区的大气降水,补给区平均气温约为7.1℃,补给高程约为1350m;估算的热储温度为48~50℃,热水循环深度为1070~1137m;硅-焓模型计算出冷水混入比例为82%。Geothermal water in the Yangjiawangeothermal well, Xinpu area, Zunyi, northern Guizhou, was used as the research object todiscuss the genesis of geothermal water based on the hydrochemical composition and hydrogen-oxygen isotope characteristics of geothermalwater.The hydrochemical type of geothermal water is SO42--Ca·Mg type, the beneficial elements are mainly Srand F. The originof geothermal water is atmospheric precipitation recharge in the Dalou Mountain area, with its recharging elevations of 1350m, and thetemperature of the recharge areas is approximately 7.1℃. The estimated thermal storage temperature is 48~50°C and the depth of hotwater circulation is 1070~1137m. The percentage of cold water mixing in geothermal water was calculated to be 82%by silicon-enthalpymodeling.
