As a kind of clean renewable energy, the production and utilization geothermal resources can make great contribution to optimizing energy structure conservation emission reduction. The circulating heat extraction process working fluid will disturb equilibrium state physical chemical fields inside reservoir, involve mutual coupling transfer, flow, stress, reaction. Revealing mechanism flow transfer reservoir during exploitation provide important theoretical support for efficient resources. This paper reviews research advances multi-field model in over past 40 years. thrust this is on objective analysis evaluation importance each its influence performance. Finally, we discuss existing challenges perspectives promote future development model. An accurate understanding mechanism, an cross-scale modeling method, as well characterization fracture morphology, are crucial production.
