Key technology for mid-deep drilling geothermal heat extraction in the Hancheng area

More Information
  • 地热井钻取优质的地热水是采灌型地热能供暖系统的前提条件,是影响整个水热型地热能项目经济效益的最敏感因素,而钻井关键技术对地热井的成井质量具有重要意义,对地区地热产业的发展有着举足轻重的作用。根据韩城地区地热资源赋存的地质特征及开发过程中遇到的难点,在理论分析和试验研究的基础上,研究了韩城地区地热钻井施工的关键技术问题,提出韩城地区地热钻井取热供暖五大关键技术问题:防塌高效钻井技术,地热井止水工艺,酸化增产增灌处理措施,原位采灌工程优化布置,梯级换热与回灌技术。通过对生产过程中遇到的技术难题进行理论分析,提出解决问题的关键技术,对五大关键技术进行了逐一阐述。这些关键技术对于韩城地区开发利用中深层地热资源具有重要的科学与工程意义,也可为其它地区提供借鉴。
