Summarized the recent progress of field tests on enhanced geothermal systems and systematically summarized and analyzed the main indicators of reservoir performance and its influencing factors. It is pointed out that the research focus on future enhanced geothermal system reservoir performance lies in four aspects: accurate measurement Reservoir excitation volume and heat transfer area, to overcome the loss of water flow and short-circuit, monitoring reservoir dynamic performance, accurate simulation and prediction of reservoir fracturing effect. The above four aspects are of great significance to improving the theory and technology of stimulation and evaluation of enhanced geothermal system reservoirs.
