北京国子监JR-181地热井施工工艺及开发评价

Drilling Technology and Exploration Evaluation in the Geothermal Well Construction in the Guozijian Region,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。经过科学合理的勘查、设计和施工,成功完成JR-181地热井。施工过程中,成功处理钻杆断裂、卡钻-坍塌、裸孔成井塌孔堵孔及出水量小等问题,保证了钻进过程进行。该井最终成井深度3700.88 m,日出水量519.18 m^3,出水温度69.3℃,通过验收并被评为优质井。该项目不仅填补了该地区无成功地热井的空白,也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-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 m^3,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.
