封储二氧化碳泄漏监测技术的研究进展

Research Progress on Leakage Monitoring Technology for CO2 Storage

二氧化碳(CO2)的持续排放被认为是目前全球变暖的主要原因之一,而CO2捕集与封存(CCS)技术是近年来提出的一种大规模、低成本的碳减排技术。在CCS技术中,由于封存在地下的CO2可能会发生逃离封存区域、向封存位置以外的区域泄漏或渗漏的现象,一旦发生泄漏,将会对环境以及周围生物造成影响,甚至破环生态环境平衡,所以对于可能泄漏或渗漏CO2的监测与识别是CCS系统安全保障的重要环节。概述了CCS技术及其发展历程,分析了CO2地质封存潜在的泄漏风险,并总结了目前国内外在封储CO2泄漏监测技术或方法方面的研究进展,为CO2以及天然气等其他气体封储安全监测提供理论支持。

CO2 is regarded as one main cause of global warming and CCS(Carbon Storage and Storage)is a new technology proposed in recent years to reduce CO2 emission effectively in a large scale.However,trapped CO2 will escape from the storage site and leak into the environment.Carbon dioxide leakage will affect the environment and surrounding organisms,and even break the balance of the ecological environment.Hence,it is important to monitor and identify the leakage or seepage of CO2 in CCS project.This paper summarizes the development of CCS technology,analyzes the potential leakage risk of CO2 geological sequestration,and summarizes the current research progress in the leakage monitoring technology of storing carbon dioxide at home and abroad.
