摘要:

This article summarizes the principal characteristics of the natural fluid circulation system at the Sumikawa Geothermal Field in northern Japan and relates them to local geological structure. Extensive two-phase flow prevails at intermediate depths (500 to 1000 m), and a very high transmissivity zone is present below a depth of about 1 km. This zone contains fluids with temperatures exceeding 300°C and is a suitable target for possible future development.
