北京小瓦窑村JR-203井地热资源开发利用的评价与分析

GEOTHERMAL RESOURCES EXPLOITATIVE EVALUATION AND ANALYSIS OF NO.JR-203 GEOTHERMAL WELL IN THE XIAOWAYAO VILLAGE,BEIJING

地热资源作为新型可再生能源,可缓解北京经济发展与环境保护的矛盾。经过科学合理地勘查、设计和施工,在北京小瓦窑村成功完成JR-203地热井的建设施工。该井成井深度3 351 m,日出水量668 m3/d,出水温度48℃,成井效果优于设计要求并具备进一步开发利用的潜力。通过结合项目区实际热水需求,并考虑JR-203井地热资源潜力,对该井地热资源的开发利用进行有效的评价与分析。该工作不仅丰富了该地区地热资源开发利用的经验,创造了显著经济价值与环保效益,并对在北京城区内推广地热资源起到积极作用。

As a new type of renewable energy,geothermal resources can solve the contradiction between economic development and environmental protection in Beijing. After scientific and reasonable investigation,designation and construction,the JR-203 geothermal well has been successfully completed. The depth of well is 3351 m,the well yield per day is 668 m3/ d,the temperature of water is 48 ℃. With these conditions,the JR-181 geothermal well has been evaluated as high-quality geothermal well which has highly potential to be explored. To meet requirement of heat,the exploitative evaluation has been done to analyze by considering on geothermal potential of this well. To create a significant economical and environmental benefits,the project has improved experience of geothermal utilization in the Xiaowayao Village,Beijing. In addition,it plays an positive role to promote geothermal resources development in Beijing.
