摘要
增强型地热系统(简称EGS)是目前地热领域的重要发展方向,EGS研究受到了发达国家的普遍重视.本文考察了EGS的勘查选址原则和国际典型案例,并结合我国地热资源分布特征,评估各地热资源分布区的开发潜力,探讨不同地热带EGS选址的可能性.最终将我国进行EGS项目的选址地区分为三类:优先开发利用区、勘探开发区、综合调查区.为我国EGS开发可行性评价等基础研究及项目实施提供参考.
As one of the most promising geothermal technologies, Enhanced （or Engineered） Geothermal System （EGS） has been regarded as an important trend in the field of geothermal. The research to EGS has attracted much attention from developed countries. In this paper, we examined the principles of survey site and the representative cases around the world, and then introduced the features of geothermal resources distribution in China. We evaluated the production potential of geothermal resources in the different areas and discuss the possibilities of EGS location for the different geothermal areas. Finally, the sites of EGS projects in China could be categorized as exploitation and utilization area, exploration development area, and comprehensive survey area. This could be taken as reference for fundamental researches for evaluating the feasibility of EGS exploitation and the implementation of EGS proiect in China.
