摘要
增强型(或工程型)地热系统(简称EGS)是指从地下3~10km低渗透岩体中经济开采深层地热的人工热能系统,主要用于发电.作为目前地热领域的重要发展方向,其研究受到发达国家的高度重视,但我国对增强型地热系统的研究还基本处于空白.本文从增强型地热系统的概念和开发思路入手,总结资源勘查、人工储层建造、地热田生产以及监测等阶段需要的科学与工程方面的关键技术及研究现状,对于提高深层地热认识,明确未来的技术发展方向具有重要意义.
The concept of Enhanced geothermal systems (EGS) is defined as engineered reservoirs that have been created to extract heat for electric power production at depths from 3 to 10 km economically. As an important field of current geothermal development, the research is full of interest to many developed countries, but China is still in its infancy. In this paper, the concept of EGS and its creation line are introduced at the beginning, and then sum up the scientific and engineering needs of the key technologies and their status during the resource exploration, reservoir creation, wellfield operation and monitoring stages. It is meaningful to improve the understanding of the deep geothermal resource and detecting the direction of technology development in the future.
