Drilling technology for recharge wells in shallow geothermal energy development—A case study of the new districts in the east and west of Zhengzhou

  • 地下水回灌是浅层地热能开发利用中不可缺少的环节,回灌井是实施回灌的关键设施,其施工技术是影响回灌效果的重要因素。选取郑州市东部新城区、西部新城区浅层地热能开发的回灌井为研究对象,分析不同区域地质条件的差异,通过回灌井结构分析地下水的回灌机理,论述影响回灌效果的因素。结合试验井施工情况,论述泥浆正循环钻进、泵吸反循环钻进、冲击钻进等不同钻进工艺的适用条件和施工中存在的问题,以及钢筋砼管、钢管和U-PVC管等不同成井管材对回灌效果的影响,探索提高单位回灌量的针对性措施,为今后郑州市及周边地区浅层地热能开发回灌井的施工提供参考。
