The invention discloses a novel horizontal well terrestrial heat recharging method. The novel horizontal well terrestrial heat recharging method comprises the following steps that 1, selecting a terrestrial heat recharging research area with the proper temperature and flow; 2, establishing geothermal recharge numerical simulation models of two different well types by adopting numerical simulationsoftware; 3, performing comparative analysis, and proposing a proper recharging scheme; 4, implementing a recharge scheme, and comparing and analyzing data; and 5, according to data analysis, drawinga conclusion, in order to keep or improve the reservoir pressure and keep the high recharge rate and reservoir temperature, preferentially adopting a recharge scheme of different-layer horizontal wellrecharge vertical well mining with the well distance being 600 m and then adopting a vertical well different-layer one-recharge one-mining recharge scheme. The novel horizontal well terrestrial heatrecharging method is good in comprehensive utilization effect, pollution of terrestrial heat tail water to the environment is relieved, the reservoir pressure can be kept or increased, and the high recharging rate and the high reservoir temperature are kept.
