摘要
以沙坪坝区虎溪镇大学城地热水资源为研究对象,采用热储法计算其地热资源放热量。首先对区域内地形、地貌以及地热水形成条件进行综合分析,并通过对丰水期、平水期、枯水期3个水期进行(抽)放水试验,得到水力性质、出水量、水温、水位等指标。其次计算相关水文地质参数,确定枯水期最大降深放水时影响半径,最大允许开采量。并在此基础上建立热储概念模型,运用热储法进行评价,从而得出按使用期100年计算热储总放热量,折合成标准煤量以及共可减排CO2量。虎溪镇大学城地热水资源丰富,开采可达到良好的节能减排效果,热储法简便可行,对类似地区的地热资源量的计算具有指导意义。
In order to develop and utilize geothermal water resources more reasonably,accurate evaluation is the key and difficult point in the development and utilization of geothermal water resources.This paper takes the geothermal water resources in Huxi University Town of Shapingba District as the research object,and the thermal storage method is used to calculate the heat release of geothermal resources.The regional terrain,landform and formation condition of geothermal water are analyzed.Indexes,including hydraulic properties,water yield,temperature and water level are obtained by pumping and drainage test in different seasons.The calculation results of the relevant hydrogeological parameters show that the impact radius of the maximum drawdown in the dry season,and the maximum allowable mining capacity.By building the conceptual model of thermal storage,the stored heat calculation shows that total heat of thermal storage can release energy for converting into standard coal and reduce the exhaust of CO2 during the one-hundred-year serviceable life.It is obvious that the geothermal resources are very rich in Huxi University Town,the development and utilization of geothermal water resources play agood role in energy conservation and emission reduction,and the thermal energy storage method is simple and feasible,it provides a guidance for the calculation of the geothermal resource reserves in similar areas.
