北京市地热资源开发利用状况

Exploration and Utilization Status of Geothermal Resources in Beijing City

北京地区有丰富的低温地热能源,有开发潜力热储面积已达到2760km2,共分为10个地热田,其中最著名的是城区地热田和小汤山地热田。北京地区地热水中富含多种对人体有益成分,被直接用于采暖、洗浴、温室种植、养鱼、温泉疗养及休闲娱乐等,产生了巨大的环境、社会及经济效益。介绍了北京地区区域地质条件,分析了热储及地热水特征等,对北京地区的地热开发利用历史进行总结,并讨论了在地热直接应用过程中遇到的各种问题,以及影响地热资源可持续开发利用的相关因素。

Beijing City is rich in low-temperature geothermal resources, and the area identified with geothermal potential has been 2 760 km2 , divided into 10 geothermal fields, including two most famous sites, urban area and Xiaotangshan geothermal fieids. The geothermal water contains many components that are beneficial for human, and is directly used for heating, bathing, planting in green house, fishing, hot spring convalescence, leisure entertainment and so on, which brings huge environmental, social and economic benefits. The geological condition, the characteristics of the geothermal reservoirs and geothermal water in Beijing are introduced and analyzed, and the history of geothermal exploration and utilization is summarized, the problems of directly using geothermal resource and some relative factors which affect the sustainable development of geothermal resource are discussed.
