Hot dry rock is a dense rock mass with a burial depth of 3–10 km and a temperature range of 150–650 °C. It primarily consists of different metamorphic or crystalline rock mass types, including granite, biotite gneiss, and granodiorite (Lu and Wang, 2015).Geothermal well tests find granite is a typical hot dry rock type (Fox et al., 2013; Yong, 2011; C Zhang et al.,
