| 摘 要： | 美国能源部正在实施干热岩“地热能前沿瞭望台研究计划”(FORGE计划)。它是以经典干热岩定义的干热岩勘查开发为约束，通过增强型地热系统(EGS)示范工程建设实践，形成新一代EGS试验平台。美国本着“可复制的结果=巨大的潜力”的理念，实现干热岩勘查开发技术新突破，以满足美国1亿家庭绿色电力供应为实际应用目标。中美典型EGS场地勘查现状对比结果表明：犹他州米尔福德与青海省共和县恰卜恰两个典型EGS场地具可比性，大致处于“并跑”的水平；在天然裂隙系统、原位地应力场、压裂参数获取与压裂方案制定等方面，米尔福德EGS场地有所超前。据此建议有关部门加快青海省共和县恰卜恰EGS场地进入勘查开发阶段，以提高我国干热岩勘查开发技术水平，早日实现EGS工程化。

| Abstract: | The Frontier Observatory for Research in Geothermal Energy (FORGE) initiative by the United States Department of Energy is to form a new generation of enhanced geothermal system(EGS) test platform based on the construction practice of EGS demonstration project. It is guided by the constraints of classic hot dry rock exploration and development and the conception of “Reproducible Results=Tremendous Potential”. It aims to achieve a new breakthrough in U.S. hot dry rock exploration and development technology in order to meet the green electricity consumption of 100 million households in the United States. A comparison of typical EGS site exploration status in China and U.S. demonstrated that the Milford EGS site in Salt Lake City, Utah and Gonghe EGS sites in Qinghai Province are competitive in technological development. However, the Milford EGS site is more advanced in natural fracture system investigation, in situ stress field test, parameter acquisition and fracturing scheme establishment. Thus, we have suggested relevant institutions to speed up the Gonghe EGS site exploration and development to quickly improve EGS technology level and achieve EGS engineering in China. |
