Fiscal 1982 Sunshine Project research report. Development of bore hole measurement technology; 1982 nendo koseinai sokutei gijutsu no kaihatsu seika hokokusho

Abstract

This report summarizes the fiscal 1982 research result on development of measuring instruments for information collection in geothermal bore holes under high-temperature high-pressure conditions. In development of high-temperature well logging cable, the new TFE Teflon insulated well logging cable (3,300m) applicable up to 320 degreesC was prepared. In development of digital well logging system, the data analyzer for edition and analysis of recorded digital logging data, the depth panel with an automatic depth correction mechanism, and the fiber optics controller were prepared. Preparation of the whole digital well logging system was thus completed. Field test was made at 3 wells in 2 geothermal areas. At the test well in Nigori-Gawa area, Hokkaido, performance test was made on the digital well logging system, TFE Teflon well logging cable, and improved winch completed in this fiscal year. At the same time, the radioactive well logging test using radioactive isotope showed the satisfactory result except neutron well logging. (NEDO)
