| 摘 要： | 以某地下水源热泵系统工程为例，依据实测渗水试验及抽水一回灌试验数据，建立研究区地下水流数值模拟模型，分析了该地区适宜的井群布置方式及井间距，并定量研究了该布置方式下对地下水流场的影响，为该地区浅薄含水层地温能资源的开发利用提供技术支撑。结果表明：该类浅薄含水层地温能开发利用井群布置方式中，抽水井布设在地下水流场的下游、回灌井布设在地下水流场的上游更为适宜，合理井间距确定为110m；在适宜井间距条件下，对水位最大影响范围约为6．50km2，温度变幅大于1℃的最大范围约为0．28km2。 |

| Abstract: | Taking an groundwater source heat pump project as example, and on the basis of field test data of infihration test and pumping - injection test, the paper establishes numerical simulation model of groundwater flow, determines the optimum distribution of heat pump wells and well spacing, and analyzes the influence of the distribution on groundwater flow. The result indicates that it is better to set the pump well in the lower course and the injection well in the up course, and the optimum well spacing is 110m. With is distribution, the influence rage is as large as 6.50 km2 , while within 0. 28 km2 the temperature variation is more than 1℃. The study provides technical basis for the further exploration and utilization of geotemperature energy of shallow aquiger. |
