CO_2封存及其地球物理监测技术研究进展

Research progress of carbon dioxide capture and store technique and geophysical monitoring research

随着温室效应加剧,CO2排放量的控制日益受到重视,CCS(Carbon Capture and Store,简称CCS)技术被看作是最具潜力的解决方案之一.其主要包括捕捉、运输、封存、监测等主要环节,封存中的地质封存适用性最好.CO2地质封存后,需在地表监测其泄漏运移情况,这是CCS技术能够成功的关键之一.本文概述CCS技术及其研究进展,并分析介绍了CO2的监测技术,重点阐述地球物理监测技术及发展状况.微动技术作为具有潜力的监测新方法正日益受到重视.

With the serious greenhouse effect,people pay much attention to control the emission of CO2.CCS technique is one of the most potential solutions.It contains capture,transport,storage and monitor.Specially,geological storage is the best applicable method among the storage methods.After injection of CO2 into underground,it need monitor the migration and leakage of sequestrated CO2.This is the key to achieve the success of CCS technique.This paper introduces CCS technique and its research progress, analysis and introduces the monitoring techniques of CO2. Among the monitoring techniques,this paper introduces the geophysical monitoring techniques specially and their development. Microtremor technique is a new method which is used to monitor the migration and leakage of sequestrated CO2.This method is paid much attention because it is a new potential monitoring technique.
