摘要：
干热岩（HDR）是一种没有水或含有少量水的高温岩体，保守估计地壳中3~10 km深处干热岩所蕴含的能量相当于全球所有石油、天然气和煤炭所蕴藏能量的30倍。增强型地热系统（EGS）是指通过水力压裂等工程手段在地下深部低渗透性干热岩体中形成人工地热储层，采出相当数量热能的人工地热系统。EGS的研究与开发已有40年的历史，但早期只局限在美国、英国、法国、日本、澳大利亚等国家，我国这方面的研究于近几年起步。目前干热岩的开发面临诸多挑战，如大体积人工裂隙热储的建造、实现EGS商业化需要进一步研究和技术开发等。本文回顾分析了国际上重要EGS示范场地建设和研究过程中所取得的经验和积累的教训，讨论了我国近几年的研究进展，希望为我国今后EGS研究和工程化示范提供参考和借鉴。
