Abstract

Abstract While geothermal energy provides the only base-load power among renewable energy sources, its development has been carried out predominantly in volcanic area. EGS (Enhanced Geothermal System) is a ubiquitous technology that can allow the geothermal power generation virtually in any area. This manuscript introduces the current state-of-the-art of EGS development in the world and presents the hydraulic stimulation technology and associated microseismicity which are key technical component in EGS. Finally this paper suggests the key research areas required in Korea for further development of EGS.

EGS发电和液压增产

Abstract While geothermal energy provides the only base-load power among renewable energy sources, its development has been carried out predominantly in volcanic area。EGS (Enhanced Geothermal System) is a ubiquitous technology that can allow the Geothermal power generation virtually in any area。This manuscript introduces the current state-of-the art of EGS development in the world and presents the hydraulic stimulation technology and associated microseismicity which are key technicalcomponent in egs。Finally this paper suggests the key research areas required in Korea for further development of EGS。Key words Geothermal energy, EGS (Enhanced Geothermal System)， Hydraulic stimulation, Hydraulic fracturing, Hydrauilc shearing超绿地热能源是提供基底负荷的新再生能源，但是到目前为止，大部分地热发电都是在火山地带进行的。人工底流层地热系统(Enhanced Geothermal System, EGS)被认为是使非火山地带的地热发电成为可能的概念，其核心是水利刺激。本论文介绍了EGS地热发电的开发现状，介绍了以水压粉碎和修理传单为主要机制的修理刺激的核心原理、设计变数及伴随修理刺激发生的微小振动的原理及观测技术。在此介绍EGS地热发电在韩国所必需的课题，为今后的技术开发指明方向。
