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.

Key words
