摘要
地热资源为绿色清洁能源,具有节能环保、可持续利用的特征,其开发利用可加快地方旅游经济的发展。刘东楼地区位于日照-青岛断裂以东,构造较发育,成热地质条件良好。本文通过浅层地温测量、物探、测温孔等手段,查明了该地区热储特征及埋藏条件,并建立了热储概念模型;根据模型分析,地下水受深部热源加热、温度升高,遇构造交会形成凝滞,与围岩发生溶滤,形成了具有较高温度和矿物质的地热流体,最终沿断裂破碎带传输至地表,形成了地热异常区;浅层地温测量显示区域恒温带埋深25~35m,恒温层温度16.2℃,测温孔地温梯度为2.12℃/100m,同时分析了研究区地热流体化学组分特征,通过地热流体质量评价显示,研究区地热水主要的开发利用方向为理疗洗浴、采暖等。最后对该地区的开发利用可行性进行了分析,以期为同类花岗岩地区寻找地热资源提供借鉴。
Geothermal resources are green and clean energy,with the characteristics of energy saving,environmental protection and sustainable utilization.Its development and utilization can accelerate the development of local tourism economy.Liudonglou area is located to the east of Rizhao Qingdao fault.Affected by it,the structure is well developed and the geological conditions of thermogenesis are good.In this paper,by means of shallow geothermal measurement,geophysical exploration and temperature measurement hole,the characteristics and burial conditions of heat reservoir in this area are found out,and the conceptual model of heat reservoir is established.According to the model analysis,the groundwater is heated by deep heat source,the temperature rises,and forms stagnation when encountering structural intersection area,and dissolves with surrounding rock,forming geothermal fluid with higher temperature and minerals,Finally,it is transported to the surface along the fracture zone,The results show that the buried depth of the constant temperature zone is 25~35m,the temperature of the constant temperature zone is 16.2℃,and the geothermal gradient of the temperature measuring hole is 2.12℃/100m.At the same time,chemical composition characteristics of geothermal fluid in the study area are analyzed.According to quality evaluation of geothermal fluid,main development and utilization directions of geothermal water in the study area are physical therapy,bathing,heating,etc.Finally,the feasibility of the development and utilization of this area is analyzed.It will provide some references for searching geothermal resources in similar granite areas.
