FY 1974 Report on results of Sunshine Project. Research and development of methods for wide-area thermal structure exploitation; 1974 nendo koiki netsu kozo chosaho no kenkyu kaihatsu seika hokokusho

Abstract

The project of (research and development of methods for wide-area thermal structure exploitation) is to pursue (1) development of heat flow rate analyzers, and researches on the methods for measurement/analysis of heat flow rates, (2) researches on geological thermometers with the cores collected from test bores as the samples, (3) observation/analysis of microearthquakes, and application of the results to the geothermal structure exploitation, and (4) development, on a trial basis, small, light air drilling machines. The method for clearly elucidating thermal structures has not been well established. Therefore, a test bore was drilled to measure temperature and collect the core samples in the wide-area geothermal district at Kita Yahata-daira as the model district, for measurement of heat flows, and analysis of the cores to estimate temperature at which they are formed. Microearthquakes, which frequently occur in geothermal areas, are also observed for extended periods. This project of (research and development of methods for wide-area thermal structure exploitation) is aimed at, based on the above efforts, to estimate/elucidate depth of thermal sources by the geological, geophysical and geochemical studies, relationships between geological structures and high-temperature zones, geothermal propagation structures, and geothermal reserves. This report summarizes the R and D results in  More>>
