Abstract: The Rehai geothermal field was taken as the geological background, the influence of well spacing, injection flow rate and temperature, and reservoir permeability on the heat extraction performance of the enhanced geothermal system were analyzed by using the orthogonal design method, and also the mutual influence between these factors. The results show that the injection flow rate is the key factor affecting the heat extraction performance and has a significant impact on the determination of injection temperature and well spacing. The larger the injection flow rate is, the shorter the stable heat extraction time and operating life are. The smaller the change of injection flow rate (increase 0.06 m3/s) is,the greater the impact will be on the heat extraction temperature (decrease 47 ℃); Increasing the injection temperature can improve the heat extraction temperature and operating life; however, the effect is limited. When the injection temperature is increased by 30 ℃, the heat recovery temperature is only increased by 10 ℃ after 50 a. The effects of well spacing, permeability, and production pressure on the heat extraction performance are similar and much smaller than the injection flow rate.

Key words: enhanced geothermal system, well pattern design, numerical simulation, parameter optimization
