【摘要】 为了开发利用天然气水合物资源,需要深入了解多孔介质中天然气水合物的分解规律。对国内外近几年有关多孔介质中气体水合物的分解方法如热激法、降压法、注化学剂法、二氧化碳置换法等进行了综述,指出了各种方法的优缺点,并总结了水合物分解模型的研究进展,同时提出了关于多孔介质中水合物分解研究方向的建议。更多还原

【Abstract】 Natural gas hydrate is widely distributed in the permafrost and marine sediments all over the world.In order to exploit and utilize it,the mechanism of dissociation in porous media should be mastered.This article summarized the dissociation methods of the gas hydrate in porous media at present,such as thermal stimulation,depressurization,chemical injection and carbon dioxide replacement.The advantages and disadvantages of each have been discussed.It provides the research progress on the dissociation model of gas hydrate,and gives some suggestions on the development.更多还原
