摘　　要：碳捕集与封存(CCS)技术是解决全球气候变暖的一项潜在可行技术,而注入CO2的流动监测对长期封存极其关键。总结了美国能源部赞助的核心研究与开发工程、国际性工程和区域碳封存合作工程使用的地下监测技术,包括模拟方法、地震方法、测井方法、环空压力监测与地球化学方法的基本原理及试验情况,得出不同地质条件下使用不同的监测方法,对我国未来CCS工程实施商业化推广具有重要指导意义。Carbon capture and storage is a potential and feasible technique to solve global warming, while flowing monitoring of injected CO2 is essential to long-term storage. Therefore, subsurface monitoring methods which are used by Core Research and Development, International Projects and Regional Carbon Sequestration Partnerships sponsored by U.S. Department of Energy are de- scribed in this paper, including the fundamental principle and test experience of simulation methods, seismic surveys methods, well logging, annulus pressure monitoring and geochemical methods. It can be concluded that the monitoring tools in different geologic conditions are distinct, which has the important guiding sense in carring out the commercial promotion of carbon capture and storage in our country in the future.
