Fiscal 1991 geothermal development promotion energy.. Report (35) on sampling/analysis of geothermal fluids (Mizuwake-Toge south area); 1991 nendo chinetsu kaihatsu sokushin chosa.; Chinetsu ryutai no saishu bunseki hokokusho (35) (Mizuwake Toge nanbu chiiki)

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>>
