摘要

A three-dimensional numerical model of the geothermal reservoir at the Sumikawa field was developed using inversion analysis with iTOUGH2 simulator. A sensitivity analysis for the reservoir rock type parameters (mainly permeability) was performed, and the priority of parameters to be estimated was determined through natural state simulation. After the sensitivity analysis was completed, inversion analysis was performed for the natural state and for a period of 20 years after the beginning of production activity. Rock permeabilities were estimated from measured temperature and pressure data in the natural state and from specific enthalpy and flow rate during production. Simulated temperatures and feed zone depth pressures in wellbores were compared with measurements to test goodness of fit. Simulated specific enthalpy during the production period was also compared with measurements using production and reinjection history matching.
