Abstract: 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-181 geothermal well has been successfully completed.In the processing of construction,successful treatments of drill pipe fracture,drill tool sticking,well blocking with collapse and the small amount of water yield,it ensured the drilling to be processed on schedule.The depth of well is 3700.88 m,the well yield per day is 519.18 m³,the temperature of water is 69.3 ℃.With these conditions,the JR-181 geothermal well has been evaluated as high-quality geothermal well.This project has end up the history that there is no geothermal well in the Guozijian region,Beijing.In addition,it plays an positive role to promote geothermal resources development in Beijing.
