【摘要】 以开发中深层地热能为背景，首先回顾常规BHE取热性能的研究现状；然后分别从改造井筒、改进BHE结构和地下水渗流的增强作用3个方面，定性和定量综述提高BHE取热能力的措施及其强化程度，以期为进一步研究和发展地埋管取热技术提供参考。更多还原

【Abstract】 With the background of developing mid-deep geothermal energy, the current research of the conventional borehole heat exchanger(BHE) is reviewed firstly. Then, the measures to improve the heat extraction capacity of BHEs are discussed qualitatively and quantitatively from three aspects, including the modification of the wellbore, improvement of the BHE structure, and enhancement of groundwater seepage. It provides a reference for promoting the development and application of BHE technology.更多还原
