| 摘 要： | 抽、灌井对之间的距离是地下水源热泵采能工程设计中的重要参数之一。该文应用数值模拟的方法对不同井对间距条件下地下含水层采能区温度场的演化进行了定量模拟,并对地温场的演化规律与井对距离之间的关系进行了理论分析。研究结果表明,抽、灌井对距离越大,抽水井温度变化速度越迟缓,且温度变幅越小。其原因是:井对距离越大,渗流区水动力影响范围越大,抽、灌区等效渗流速度越小,回灌水向抽水井运动过程中散热(吸热)越充分。

| Abstract: | The distance between production and injection wells is a key parameter for the design of energy abstraction systems using groundwater source heat pumps.A numerical model was developed to quantitatively simulate the changes of geo-temperature field due to energy extraction with various well distance.The simulation results showed that the larger the well pair distance the slower and the smaller the changes of production well temperature,because the equivalent velocity of production and injection induced groundwater movement will decrease and the groundwater can absorb or release much more heat as the well distance increases,and vice versa. |
