摘要
为研究银川盆地的浅层地温能热响应,选取永宁县闽宁镇和贺兰县纺织园两地作为试验区进行分析。采用地埋管试验孔热响应试验,通过原始数据收集、数据预处理、数据分析、结果验证与修正等数据分析过程,测得两试验区孔域的岩体初始平均温度,通过大小功率恒热流试验测得平均综合导热系数,并进行模拟夏季和冬季的恒温度测试。根据测得的排热量和取热量计算出单位孔深换热量永宁县闽宁镇为59.2 W/m、-43.8 W/m,贺兰县纺织园为57.6 W/m、-25.7W/m。从数据结果对比来看,永宁县闽宁镇的各项试验数据均高于贺兰县纺织园,为该地区浅层地温能资源评价及浅层地温能开发利用适宜区评价提供依据。
In order to study the thermal response of shallow geothermal energy in Yinchuan Basin,two places,Minning Town in Yongning County and Textile Park in Helan County,were selected as the experimental areas for analysis.Using the thermal response test through buried pipe test hole,the initial average temperature of rock mass in two test areas was measured by data collection,pre-processing and analysis,results verification and correction and other data analysis processes,the average comprehensive thermal conductivity was measured by constant heat flow test with large and small power,and the constant temperature tests simulateing summer and winter were carried out.According to the measured heat dissipation and extraction,the unit depth heat transfer in Minning Town,Yongning County,is 59.2 W/m and-43.8 W/m respectively,while in Textile Park,Helan County,it is 57.6 W/m and-25.7 W/m respectively.From the comparison of data results,all experimental data in Minning Town,Yongning County are higher than those in Textile Park,Helan County,which provide a basis for the evaluation of shallow geothermal energy resources and the assessment of suitable areas for shallow geothermal energy development and utilization in the region.
