摘　　要：针对目前地源热泵会对采能区地下水热量运移造成一定影响的问题,通过数值模拟的方式,对地源热泵工程含水介质水-热耦合运移进行模拟,并对井群进行优化处理.通过比较不同井距、加设帷幕、水流影响等情况下地源热泵运行的水-热运移结果,讨论热贯穿问题.综合考虑避免热贯穿的多方面因素对井点布设进行优化,得出最合理的井距、抽注水轴线与地下水流的角度、是否设置帷幕以及抽注层面选择等方案.对合理指导地源热泵的井点以及井群布设具有很好的意义.For the problem that the ground-source heat pump can affect groundwater thermal transport in energy mining areas,the thermal-hydro coupled transport of water-bearing media in groud-source heat pump projects was simulated and the well group was optimized by numerical simulations.The issue of heat penetration was discussed by comparing thermal-hydro transport results of the gound-source heat pump operation under the situations of different well spaces,adding curtains and effect of currents etc.Considering various factors avoiding heat penetration,well point arrangements were optimized to obtain these schemes of the most reasonable well space,the angle between the axis of pumping water and groundwater flow,setting curtains whether of not as well as pumping layer selections.It would be a good guidance for reasonably deploying well points and well groups of ground-source heat pumps.
