Summary:PROBLEM TO BE SOLVED: To improve accuracy in analyzing a state of a geothermal fluid circulation system. SOLUTION: In the geothermal fluid circulation system 30, product fluid PF is introduced from a production sector 31 to a water separation part 32, and hot water separated in the water separation part 32 is returned into the ground as returned fluid. An analyzer for the geothermal fluid circulation system 30 uses each of circulation rates f1, f2and an increased temperature Theatup(a temperature increase by a recovered heat amount when second circulation fluid RF 2 flows in the production sector 31) as unknown variables, in a concentrated constant model wherein at least part of the returned fuel flows into the production sector, and sets a balance expression relating to mass and energy of the geothermal fluid in the production sector 31 as a primitive equation. The analyzer performs history matching with respect to a product fluid temperature TP, Cl concentration [Cl]P, and SO4concentration [So4]Pby the theory of Kalman filter based on the basic equation.
