摘要
湖南省地下热水资源丰富,已发现热水单元116处,以低温地热资源为主,占98.3%,中温热水资源仅占1.7%;地下热水主要分布于湘西北、湘中、湘东北、湘东、湘东南5个区。全省地热资源总量为27.93万m3/d,每年可提供利用的热能量约14.59×109MJ。地下热水中微量元素丰富,有80处达到饮用天然矿泉水标准,达标元素为偏硅酸、锂、锶、锌和溶解性总固体等。目前,我省地热资源开发利用方式较原始,开发利用程度较低、用途单一,有待于进一步开发利用。
underground hot water resources are abundant in Hunan province, 116 hot water units have been found, mainly low-temperature geothermal resources, accounting for 98.3 %, and mediumtemperature hot water resources accounted for only 1.7 %;Underground hot water is mainly distributed in five districts: Northwest Hunan, Central Hunan, Northeast Hunan, Eastern Hunan and Southeast Hunan. The total amount of geothermal resources in the province is 279,300 m3/d, and the annual thermal energy available is about 14.59 × 109MJ.There are abundant trace elements in underground hot water, and 80 places meet the standards for drinking natural mineral water. The standard elements are partial silicate, lithium, strontium, zinc, and soluble total solids. At present, the development and utilization of geothermal resources in our province is primitive, with a low degree of development and utilization and single use.
