Groundwater recharge is an unavoidable step in shallow geothermal development and utilization. The reinjection well is the key facility to carry out reinjection， and its drilling technology is an important factor affecting the effect of reinjection. Taking the recharge wells for shallow geothermal development in the new districts of eastern and western Zhengzhou as the research objects， the differences in geological conditions in different regions are analyzed. The mechanism of groundwater recharge is analyzed in the perspective of the recharge well structure. The factors affecting the effect of reinjection are discussed. With regard to test well construction， this paper discusses the applicable conditions and problems of different drilling techniques， such as mud positive circulation drilling， pump suction reverse circulation drilling and percussive drilling， as well as the impact of the reinforced concrete pipe， steel pipe and U-PVC pipe and other different well pipes on the reinjection effect. To explore the targeted measures to increase the rate of unit recharge. It provides a reference for the construction of shallow geothermal development recharge wells in Zhengzhou and its surrounding areas.
