【摘要】 本文在对廊坊市万庄镇的浅层地热资源量进行概算的基础上,对水源热泵在该区的推广可行性做了评价;并且通过野外场地试验,对该区地下水供给能力及回灌能力进行了研究。得出如下主要结论:(1)该区域浅层地热能储量丰富,总储量约为18 075.0×1010KJ,相当于标准煤616.8×104t,具备推广水源热泵的基础条件。(2)研究区浅层含水层富水性较好,水质较好、供水能力较强,满足水源热泵的运行,也利于地下水回灌,不引起水资源的浪费。(3)在不引起次生环境地质问题前提下,建议在水源热泵系统运行时单井抽水量控制在80 m3/h左右,单井回灌量不超过40 m3/h,采用一抽两灌的原则配置抽、灌井数量,抽水井和回灌井的井间距控制在70~80 m,这样能够使得被抽取的地下水基本得到回灌补给,也可合理的利用浅层地热资源。更多还原

【Abstract】 Groundwater recharge is critical to promote the application of ground-source heat pump system.This paper estimated shallow geothermal resources of the Wanzhuang town,Langfang City and carried on field tests to study gush and recharge capacity of groundwater.The results show: shallow geothermal energy is abundant in this region.Croundwater temperature changes from 17.0℃ to 19.0℃,which is a suitable temperature for ground-source heat pump system.Gushing flow of 80 m3/h for a single well is recommended for application of the system and single recharging flow should not exceed 40 m3/h.It would be best to configure two gushing well for one recharging well.Croundwater quality is quite well to meet groundwater-source heat pump system requirements.The region cannot be more suitable for the development and utilization of shallow geothermal energy.更多还原
