摘　　要：在对成井环节分析的基础上,识别了对地下水系统影响较为显著的成井工艺参数(即井径和滤水管孔隙率),基于地下水水热运移基本原理,建立了地下水流动和热量输运耦合模型。选取典型地温空调项目,通过设计不同成井工艺参数,模拟地温空调运行对地下水流场和温度场的影响。结果显示:不同井径和孔隙率在地温空调运行中,对地下水系统影响程度差别较大,井径对抽水井、回水井的影响比较明显,孔隙率对抽水井的影响大于对回水井的影响,适合安阳市地温空调的井径为30 cm、滤水管孔隙率为30%。According to the analysis of well completion process,this paper distinguished that the well completion tech-parameters (well diameter and filter porosity)could largely affect the groundwater system. Based on the fundamental principle of water and heat transfer,the coupling model of the flow of groundwater and the transport of heat was established. It selected several typical ground temperature air-conditioning projects in order to simulate the effect of ground temperature air-conditioning to the underground flow field and temperature field by design well completion technolo-gies with different parameters. From the results of simulation,it finds out that the different well diameter and filter porosity can make a great differ-ence on the effect of groundwater system. The well diameter can affect the pumping wells and recharge wells obviously,on another hand,the filter porosity parameter’s effect on the pumping wells is bigger than on recharge wells. It finds out that 30cm of well diameter and 30% of the porosity of filter are more suitable for the ground temperature air-conditioning project in Anyang City.
