昆明主城区地热井水资源特性及开发利用研究

在调查收集整理资料的基础上,分析总结昆明主城区地热井水资源分布、特性、开发利用现状。结果表明:主城区地热水井出水量大,水位下降明显,水温高,水化学类型以HCO3-Na、HCO3-Na·Ca型为主;昆明主城区地热水利用现状以洗浴、酒店、休闲娱乐为主,开发利用程度较低。建议对地热井进行动态监测,及时分析变化趋势及规律,科学合理多元化开发利用地热水资源。

Characteristics,Development and Utilization of Geothermal Well in Urban Area of Kunming

Based on the survey data, this paper analyzes the distribution, characteristics and development of the water re-sources in geothermal well in the main city area of Kunming. The results showed that the water flow rate of geothermal well is large and water level drops obviously. The water temperature is high. Thee water chemistry type is dominated by HCO3-Na type. The use of geothermal water is mainly used in bathing,hotel and recreation,and the utilization degree is low. It is suggested to con-duct dynamic monitoring of geothermal well,analyze the change trend and rules in time,and rationally diversify and exploit geo-thermal water resources.
