为促进关中西部城区地热资源开发利用,通过分析地热资源分布及热储类型,结合地热地质条件提出开发建议。分析认为,关中西部热储类型主要包括孔隙型层状热储、岩溶型层状热储和裂隙型带状热储3种类型;扶风县赋存岩溶型层状热储,地热地质条件好,适合进行水热型地热资源开发利用;渭滨区、眉县赋存有孔隙型层状热储和裂隙型带状热储,地热地质条件较好,适合进行水热型地热资源开发利用;岐山县、金台区、陈仓区、凤翔区赋存孔隙型层状热储,地热地质条件中等,可根据地热地质条件选用水热型与换热型的地热资源开发利用;陇县、千阳县赋存孔隙型层状热储,但地热资源较差,适合开展换热型的地热资源开发利用。

layered thermal reservoirs, and fractured-zone thermal reservoirs. Fufeng County has karst layered thermal reservoirs withgood geothermal geological conditions, which is suitable for the development and utilization of hydrothermal geothermal re-sources. There are porous layered thermal reservoirs and fractured-zone thermal reservoirs in Weibin District and MeixianCounty, which have good geothermal geological conditions and are suitable for the development and utilization of hydrother-mal geothermal resources. Qishan County, Jintai District, Chencang District and Fengxiang District have porous layered ther-mal reservoirs with moderately geothermal geological conditions, thus hydrothermal and heat exchange geothermal resourcesshould be selected for development and utilization. Longxian County and Qianyang County are of porous layered thermal res-ervoirs, but the geothermal resources are relatively poor, which are suitable for the development and utilization of heat-ex-changing geothermal resources.
