| 摘 要： | 地下水同井抽回井主要应用于浅层地热能开发。细颗粒地层中地下水抽回井的比例模式多数为1∶3～1∶6,不仅增加建设成本,而且造成占地面积大、管理不便和回灌困难等问题。针对该问题,通过分析和研究,利用钻探理论和水文地质条件设计了＂同井抽回两用系统＂,实现了在同一口井内抽水和回灌之目的,并在实际工程中取得了较好的效果。就钻井设备选择、成井工艺及应用效果进行了详细阐述。

| Abstract: | Groundwater pump and re-injection in the same well is mainly applied in shallow geothermal development.For GSHP system,the proportion between pump well and re-injection wells is 1∶3~1∶6,for fine particle formation,it not only means more construction cost,but also means large site area,management inconvenience and difficult re-injection.According to the analysis and research,＂pump and re-injection in the same well＂ system was designed according to the drilling theory and hydrogeology conditions,pump and re-injection in the same well was realized with satisfied effects.The paper explained ＂pump and re-injection in the same well＂ about equipment selection,well completion technology and application effect. |
