Investigation on the development and introduction of new geothermal exploration technology. Part 2; Chinetsu shintansa gijutsu kaihatsu donyu ni kansuru chosa. 2

Abstract

For the purpose of maintaining and increasing the geothermal power generation amount, the development was made of exploration technologies which become necessary in the stage of geothermal reservoir exploration and in the stage of reservoir management and peripheral development. As development technologies, the following were proposed: fracture flow characteristics exploration method (FE), production/circumference areas flow characteristics exploration method (PE), and integrated analyzing method (IA). As to FE, for the survey of geothermal fluid dynamic characteristics in fracture aggregate composing the geothermal reservoir, developments were made of the well hydraulic testing method for examining hydraulic characteristics of fracture system and of the fracture evaluation method composed of the core/logging analysis method, the permeability logging method and electroseismic exploration method. As to PE, for maintaining and managing steam production in the developmental area and developing the area to the circumference area, development was conducted of technology for exploring variations of reservoirs and fluid flow from the data on precision gravity, three-dimensional resistivity, fluid geochemistry, active seismic wave and self potential, precision electromagnetism, passive seismic wave, etc. As to IA, development was made of reservoir simulation technique, etc. 2 refs., 70 figs., 41 tabs.
