| 摘 要： | 天然气水合物广泛存在于海底沉积物和大陆永冻区,是一种潜在的能源资源。CO2置换法开采天然气水合物,不仅可以从水合物藏中开采出天然气,还能够使空气中的CO2以水合物的形式长期埋存于地下。本文从可行性、微观机理及影响因素等方面,总结了甲烷水合物CO2置换法开采的研究现状,论述了目前研究中存在的问题及不足,并对以后的研究工作提出了一些展望和建议。

| Abstract: | Gas hydrate, which occurs widely in marine sediments and permafrost areas, is a kind of po-tential energy resources. To extract natural gas from gas hydrate using CO2 replacement method can not only produce natural gas from the gas hydrate deposits, but also store CO2 underground in the form of hydrate at the same time. In this paper, we presented a review on the current research status using CO2 replacement method for exploitation of methane hydrate, including the feasibility, micro-scopic mechanism and influence factors. The problems and shortages of current research are discussed and some prospects and recommendations are provided for future researches. |
