碳酸盐岩类地层地源热泵系统适宜性研究
|
摘要
碳酸盐岩地区岩溶裂隙发育,破碎带、断层广泛分布,建造垂直换热孔难度大,热物性参数难获取,极大程度制约了地源热泵系统在该区的应用。针对铜仁奥体中心碳酸盐岩类地层,运用物探、钻探、现场热响应试验等综合手段,旨在探索地源热泵系统在碳酸盐岩地区的适宜性。主要成果有:利用物探方法对地质条件进行勘探,分析知,测区有6条断裂破碎带,无溶洞发育特征,西西南区域地层完整性好;测得岩土平均导热系数为2.85 W/(m·℃),夏季、冬季地下平均换热量分别为72W/m、65W/m;弄清垂直地埋管布孔适宜深度为120m,水源井出水量在成孔直径152mm时可达50m~3/h;对建设不同地源热泵形式进行适宜性分区,以期为地源热泵系统在碳酸盐岩地区的推广应用提供参考意见。
In carbonate area, karst fractures are well developed, and fracture zones and faults are widely distributed.It is difficult to build vertical heat transfer holes or get thermophysical parameters, which greatly restricts the application of ground source heat pump system in this area. At the carbonate stratum of Tongren Olympic Center,we use geophysical prospecting,drilling and field thermal response experiments to explore the suitability of ground source heat pump system. The main achievements are as follows: the geophysical methods is used to explore geological conditions, and the result shows that there are six fractured zones in the survey area, without characteristics of karst cave development. The stratigraphic integrity of the southwestern region is good. The average thermal conductivity of the rock and soil is 2.85 W/(m·℃). The average heat transfer rate is 72 W/m in summer and 65 W/m in winter. The suitable depth of the vertical buried tube is 120 m. And the water output of the water source well can reach 50 m~3/h when the bore diameter is 152 mm. The adaptive partition of construction for different ground source heat pumps is carried out and expected to provide reference for the popularization and application of ground source heat pump system in carbonate area.
