Shandong Peninsula is one of the Hot Dry Rock (HDR) development target sites in China. Based on the geological, geophysical and geothermal data, a final drilling position was determined. Through analyzing the logging, coring and rock test data, this study obtianed the size, temperature and temperature gradient of the deep Wendeng granite, spatial distribution of fractures, physical and mechanics parameters of the grainte. Based on these data, a 3D HDR geothermal model was established and the electricity generation was evaluated through numerical simulation. Intrusive rocks and tectonic fractures are well developed within the study area. The high terrestrial heat flow of 48~85 mW/m 2 and anomaly geothermal gradient of 5. 3~18. 59 ℃/100m all suggest preferential occurrence conditions of deep geothermal resources. The simulation results show that with an injection water rate of 30 kg/s (10 ℃) and running 20 years at the depth of 4000 m fractured reservoir, the production temperature decreased by 11. 3% from 168 ℃ to 149 ℃ and flow impedance increased to the final 0. 076 MPa/(kg/s). Annual power output of 3. 7~3. 4 MW is higher than that of Soultz project in France, indicating a huge HDR resource potential.
