In this paper,the nucleation and growth process of CO₂ hydrates are briefly introduced.The strengthening effect of nanofluids on CO₂ hydrate formation are analyzed from the aspects of induction time,gas consumption and hydration conversion rate.The influencing factors of nanofluids on CO₂ hydrate formation are discussed by the types,concentration and size of nano-particles,stability of nanofluids,and experimental conditions of high temperature and low pressure.The strengthening mechanism of nanofluids is expounded and the future research directions are prospected.
