| 摘 要： | 通过建立地下含水层水-热耦合数学模型,对不同抽灌井间距、回灌井间距以及天然水力坡度条件下的抽水井温度变化进行模拟和分析。结果表明,抽灌井间距小于120 m时,抽灌井间距对热贯通的影响程度相差很大;回灌井间距对热贯通的影响相对较弱;存在天然水力坡度时,正确的布井方式更加有利于抽水井水温的稳定。

| Abstract: | Through the establishment of the mathematical model of underground aqui- fer which couples water flow with heat transfer, the temperature of pumping well is simu- lated and analyzed with different pumping-injection wells distribution and natural hydrau- lic gradient. The simulation results show that, if the distance of pumping-injection wells is less than 120 m, the impact varies widely with different spacing; the influence of injection wells more spacing on heat transfixion is weak relatively; the appropriate wells distribution is helpful to maintain the temperature of pumping well stable. |
