文摘

Heat extraction from EGSs with heterogeneous reservoirs is modeled. A large number of cases with various heterogeneous reservoirs are simulated. Effects of reservoir heterogeneity on EGS heat extraction are analyzed. A method is proposed to properly quantify reservoir heterogeneity. An equation relating EGS heat extraction to reservoir heterogeneity is established.
