摘要：为了验证本次浅层地温场管内常温监测方法的可行性，在北京市某试验场地钻齿了一眼150m常温监测并，并内下入双U型垂直管，分别在U型管内管外相同深度市设了温度传感器。经过整测9个月地温场数据，得出该区城 150m深度地温场随深度的增加呈现先递增后递减再递增的变化趋势；管内管外同一深度平均温度差介于0℃~0.4℃范图内，130m深度处温差最大，管内比管外温度高0.4℃，40m深度处管内管外温度一样；管内管外同一深度温度走势
对比分析得出，同一深度温度变化一致，管内比管外温度变化滞后并未存在。关键词：温度传感器；U型管：地温场

Abstract: In order to verify the feasibility of the temperature monitoring method with tube in shallow geothermal field, we drilled a normal temperature monitoring well in the depth of 150 m at one test site in Beijing, and put a double U-shaped vertical tube down into the well, temperature sensors were installed inside and outside the U-shaped tube in same depth respectively. After acquiring 9-month monitoring data of the geothermal field, it can conclude the change trend deep down to 150 meters of the geothermal field in study area increases after decreasing and then increases again with the increasing of depth. Average temperature difference is in the range of 0 C -0.4 C in the same depth of inside and outside the tube. The maximum temperature difference is in the depth of 130 meters where temperature of inside the tube is 0.4 C higher than outside temperature. In the depth of 40 m, temperature is identical inside and outside tube; through the contrastive analysis of the temperature trend, no temperature
difference and no hysteresis phenomenon occurred in the same depth of internal and external tube Keywords: The temperature sensor, U-shaped tube; Geothermal field
0引言
浅层地温能是指蕴藏在地表以下一定深度范围内（一般为200m）的岩土体、地下水中具有开发利
用价值的地热能，是一种可再生的新型环保能源，利用前景广阔。由于浅层地热能资源在地下200m左右，对其开发势必会对地质环境造成一定影响，因此在浅层地温能开发利用的过程中对其进行动态监
