The current state of research on C02 sequestration and Nano cementing cement is discussed. Leaching action, carbonization action, dissolving action, synergistic action, and cement's anti-corrosion mechanism are the main components of the C02 corrosion mechanism on cement. Currently, there are three approaches to enhance cementing cement's ability to resist C02 corrosion: #properly lower the alkaline content of cementing cement; (Lower the cementing cement's calcium-silicon ratio Ca/Si); Fill the cement's internal and external pores to stop C02 contusive fluid from entering the cement. The effectiveness of the Nano cementing slurry against C02 corrosion is vehemently discussed. The use of nano-modified weel cement for C02 storage was considered. [ABSTRACT FROM AUTHOR]
