Abstract
The paper investigates acidic brine which a factor inhibiting the geothermal development, from the viewpoints of prediction, measures and effective use. The investigation predicts that the deeper the area to be developed is, the greater the possibility of spouting of acidic brine is. Its amount as resource is 13-30% of the total resource amount in Japan. As prediction technology for acidic brine, there are geological, geochemical and geophysical methods before excavation. Cores and cuttings obtained during well drilling are helpful information sources. In addition, there is a technology analyzing the origin and behavior of acidic brine. Utilization of isotopes including {sup 34}S is effective for the study of the origin. It is also necessary to compile geothermal models. In relation between alteration mineral and acidic activity, the analysis using fluid inclusion is paid attention to. To study measures for and effective utilization of acidic brine, examination should be made mainly on results form oil and gas wells and applicability of those to geothermal wells, anti-scale techniques and economical efficiency when using high-quality materials. 164 refs., 100 figs., 52 tabs.
