摘　　要：回灌井堵塞是地下水源热泵系统运行过程中经常出现的问题,由于实际工程中回灌井侧缺少相应的监测设施,使得溢井发生前难以被察觉。本文建立了地下水源热泵回灌井溢井预测诊断的模型,并以实际工程为例对回灌井溢井问题进行分析及预测。结果表明:随着回灌的持续进行,各回灌井的回灌性能均有所下降,但回灌性能的恶化程度及发生溢井所需时间各不相同。若对各回灌井的流量进行合理分配,则可从整体上降低溢井的可能性。The injection well clogging often occurs during the operation of groundwater source heat pump system. Because there is lack of monitoring facilities on the side of injection well in practical engineering, it is inconspicuous until the overflow occurs. This paper established forecast and diagnose model for the overflow of injection well of groundwater source heat pump, and took the actual projects as examples for analysis and forecast of injection well overflow. The results show that the injection wells＇ injection performance has declined along with the injection continues, but their degree of deterioration and the period of time that injection well overflow is different. If the flow rate of every injection well is distributed reasonably, it can reduce the possibility of the overall reinjection.
