| 中文摘要: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. |
