Fiscal 1980 Sunshine Project research report. Research on underground reinjection mechanism of hot water; 1980 nendo nessui no chika kangen mechanism no chosa kenkyu seika hokokusho

Abstract

This report summarizes the fiscal 1980 research result on reinjection mechanism of hot water. In the research in Takinoue area, except one well with drop of nearly 2m, no change in underground water level was observed, and no change in water temperature except seasonal change, no change in river water and no leakage of reinjected hot water were also observed. Quantitative simulation was made on hot water supply from the outside strata to storage strata, features of hydraulic structure, pressure fluctuation and water balance, using tracer test data. In Nigori-Gawa area, no clear change in water level and water temperature was found. Various basic parameter data related to water flow in rocks composing storage strata were obtained by tracer test. In the research on the effect of reinjected hot water on the ground, in Takinoue area, fine earthquake was observed on fault planes, however, the spectral analysis result showed no change in ground condition. The precise survey result showed specific fluctuation during last year. In Nigori-Gawa area, fine earthquake was equivalent to that before development. Vertical and horizontal fluctuations were also observed by precise survey. (NEDO)
