Description

technical field [0001] The invention relates to the field of design and manufacture of new energy development test equipment, in particular to a test device and a simulation method for enhanced geothermal exploitation simulation. Background technique [0002] The human demand for energy continues to grow. On the one hand, the traditional fossil energy is increasingly exhausted. On the other hand, its extensive use has brought serious impacts on the ecological environment and brought serious problems. The only way to solve the energy problem is to find new clean energy. Hot dry rock refers to hot rock with a buried depth of more than 3km, with a temperature of 150°C to 650°C, which contains a large amount of heat energy. The enhanced geothermal system is a hot dry rock resource development project, with a huge geothermal energy content and no carbon emissions. It is the most potential new energy source as an alternative to traditional energy sources. At present, countries a...
