摘　　要：函谷关周边地热资源丰富,新近系及古近系热储层具备良好的开采条件。本文以函谷关及其周边一定区域为研究区,依据地热地质基础资料,对其新近系、古近系热储层赋存条件进行了分析。首先,根据区域构造格局对研究区内新近系、古近系热储特征行了分析,分析结果显示研究区地热类型属沉积盆地传导型,古近系热储层结构受到基底北西向弘农涧河断裂的控制,使热储层的富水性在平面上存在一定的差异;其次,对研究区的地热资源储量、可开采量及热能进行了计算评价,结果显示新近系、古近系热储较适宜开发且地热田规模达到了中型;最后,对研究区地热资源开发利用方向进行了分析,结果显示研究区新近系、古近系热储层地热流体可用于采暖、洗浴、理疗、农业温室等,并且开发其地热资源具有良好的经济性。The geothermal resources around Hangu pass are abundant and the thermal reservoirs of Neogene and Paleogene have good development conditions.This article takes Hangu pass and its surrounding areas as the research area and analyzed the occurrence conditions of its Neogene and Paleogene thermal reservoirs based on geothermal geological basic data.Firstly,the characteristics of the Neogene and Paleogene thermal reservoirs in the research area were analyzed based on the regional structural pattern.The analysis results showed that the geothermal type in this area belongs to the sedimentary basin conduction type,and the structure of the Paleogene thermal reservoirs is controlled by the basement northwest trending Hongnongjian River fault,resulting in certain differences in water abundance of the thermal reservoirs on the plane.Secondly,the calculation and evaluation of geothermal resource reserves,development output amount and heat energy in research area were carried out.The results showed that the Neogene and Paleogene thermal reservoirs are more suitable for development and the geothermal field scale has reached medium scale.Finally,an analysis was conducted on the development and utilization direction of geothermal resources in research area,and the results showed that the geothermal fluids in Neogene and Paleogene thermal reservoirs in this area can be used for heating,bathing,physical therapy,agricultural greenhouses,etc.,and the development of their geothermal resources has good economic benefits.
