为研究含水层水文地质条件对循环单井的影响,通过大量算例模拟分析了循环单井在不同水文地质参数下的运行特性.结果表明:水平渗透系数较大的含水层提高了原水交换比,减轻了抽水温度的变化;对于渗透性能较好的含水层,含水层滞止导热系数对循环单井的影响不大,而对于渗透性能较差的含水层,抽水温度随着含水层滞止导热系数的增大而迅速提高.这说明含水层渗透系数是一个重要参数,直接决定循环单井抽水温度的变化幅度.
In order to study the effect of aquifer hydrogeological conditions on the single well, the operation characteristics of the single well under different hydrogeological parameters are simulated and analyzed by a large number of examples. The results show that the aquifer with larger horizontal permeability increases the ratio of raw water exchange , Which can reduce the variation of pumping temperature. For the aquifer with better permeability, the stagnant thermal conductivity of the aquifer has little effect on the single well. However, for the aquifer with poor permeability, the pumping temperature changes with the stagnation of the aquifer Thermal conductivity increases rapidly and rapidly.This shows that the aquifer permeability coefficient is an important parameter that directly determines the circulating single-well pumping temperature range.
