Abstract

The paper surveys the spouting of geothermal fluids in test boring wells, the well logging, and the status of geothermal fluids, as a part of the geothermal development promotion survey in the Mizuwake-Toge south area. In the spouting test of N3-MW-6 well, the 53rd swabbing led successfully to spouting. The spouting amounted to 3.6 tons/h in steam and geothermal water, but stopped spontaneously in 100 minutes. Results of the logging are hardly different between before and after the spouting indicating a maximum temperature of 200{degree}C, barometric pressure of 75, and water levels of a 250-300m section. The geothermal water is a neutral Cl deep-area type. N2-MW-2 well spouted immediately after the 10th swabbing, indicating steam of 3 tons/h at the stable time, geothermal water of 7.3 tons/h, pH9, Cl of 1500ppm, and the total spouting time of 4029 minutes. The place where the geothermal fluid flows in is 635m deep, and when the well head pressure was 1.7-3.9 barometric pressure, the spouted fluid temperature was 199-198{degree}C. The geothermal water is a Cl-HCO3 type. In both wells geothermal water is ground water originated from meteoric water which reacted with peripheral rocks by volcanic heating and was formed in the deep area.  More>>
