摘　　要：在西安某厂区深层地热对接井安装了埋深大于2 000 m且深度不同的2个竖向U型深埋管换热系统,应用原位实验的方法进行了换热特性的研究。实验条件为埋管进水温度和水流率基本恒定,实时检测埋管的出水温度。通过埋管进、出水温差及流率得到埋管在实验条件下的综合换热强度及不同深度地热井的实验,表明埋管深度的增加对换热强度的影响很大。A heat transfer system with two vertical deep-buried U-bend pipes at a buried depth of>2 000 m was installed on a drilled hole in one factory in Xi’an,In-situ experiments was used to conduct the heat transfer characteristics study.The experiment condition is that the inlet temperature and water flow rate in the deep-buried pipe are basically constant and the inlet and the real-time outlet water temperatures of the buried pipe were measured.Through the analysis on the inlet and temperature difference and water flow rate in the deep-buried pipe,the comprehensive heat transfer intensities were obtained in the experimental condition.By the tests in different holes,it shows that the increase of depth of buried pipe greatly affects the heat transfer intensity.
