| 摘 要： | 扎仓温泉位于青海省贵德县扎仓寺村,其开发利用至今已有600多年的历史。温泉出露于断裂带交汇部位,地下热水矿化度为1310~1390 mg/L,水化学类型属于SO4.C l-Na型。研究结果表明,温泉的补给来源为大气降水,温泉水年龄约165 a。利用S iO2温标法计算出热储温度为136℃,估算热水循环深度为1385 m。温泉的天然放热量大于1.23×1014J/a,扎仓沟地区的地热资源量达2.07×1014J以上。热水宜直接用于供暖、洗浴、温室种植和养殖等。该地热田深部尚有地热能潜力。

| Abstract: | The Zhacang hot springs,located near Zhacangsi in Guide County,Qinghai,has a utilization history of about 600 years.The occurrence of the hot springs is controlled by faults.The thermal groundwater has total dissolved solids of 1,310-1,390 mg/L,and is hydrochemically of SO4·Cl-Na type.Chemical analyses indicates that the hot springs are of meteoric origin and the residence time of hot water is 165 a.The temperature of the geothermal reservoir,which is calculated with the SiO2 geothermometer,is 136 ℃.The thermal groundwater is estimated to circulate to a depth of 1,385 m.The natural heat discharge of the hot springs is more than 1.23×1014 J/a and the geothermal resources in the Zhacanggou area is more than 2.07×1014 J.The hot water is suitable to direct use of heating,bathing,greenhouse planting and breeding.The geothermal potential also exists in the deep part of the geothermal field. |
