Abstract

Abstract: ： With the advancement of technologies in drilling, fracturing, micro-earthquake prediction and numerical simulation in recent years in science and technology and industry, commercial development and utilization of geothermal energy in hot dry rock has become possible. The practice of foreign EGS projects has a history of more than 40 years. Scientific assessment of the risks, uncertainties, and economics of EGS projects has become a key issue for commercialization. Therefore, Europe and the United States have separately developed the representative EURONAUT and GEOPHIRES software packages for scientific and engineering personnel to perform technical and economic analysis of EGS projects. Based on the updated report released by the National Renewable Energy Laboratory （NREL） in February 2018, and based on literature analysis, the paper introduces the framework, parameter system, and features of the EEG technology economic simulation tool GEOPHIRES v2.0, and introduces two different types. Applied research was conducted in the EGS project. The GEOPHIRES tool can be used as a reference for the analysis and study of the key influential factors for the development and utilization of geothermal energy in hot dry rock in China and for the improvement of the theory and methods for the evaluation of technology and economy; on the other hand, it is used for the development and preparation of dry hot rock projects adapted to China's national conditions and resource characteristics. Technical and economic simulation software has important guiding significance.

Key words: hot dry rock, EGS, technical and economic evaluation, GEOPHIRES, simulation tool
