- 摘要:
天然气水合物(可燃冰)是由水分子和气体分子(烃类为主)在特定的压力与温度条件下相互接触而形成的笼状类冰结晶化合物。可燃冰的开采一直被视作解决世界能源问题的重要途径。综述了可燃冰开采方法及研究现状,从基本原理、室内试验、数值模拟三个方面对每种开采方法进行系统概括，其中,降压法是目前使用最广、性价比较高的方法。另外,固态流化开采技术由于对我国南海海域深海可燃冰开采具有借鉴价值,因而也成为当前我国可燃冰开采研究的热点问题。同时,介绍了可燃冰矿藏现场试采现状。最后,对可燃冰的开采情况进行总结,并提出针对性建议,指出未来可燃冰的研究方向。
Natural gas hydrate (combustible ice) is a cage-like ice crystal compound formed by contact of water molecules and gas molecules under specific pressure and temperature conditions.The exploitation of combustible ice has always been seen as a vital way to solve global energy issues.This paper firstly introduces the basic characteristics of combustible ice ,then describes the current research methods and research status of combustible ice mining,and systematically summarizes various mining methods from three aspects:basic principle,laboratory test and numerical sumulation.Among them,the methdo of depressurization is the one with the most extensive application and relatively higer cost performance at present,and solid fluidization mining technology has become a hot issue in China's flammable ice mining research due to its reference value to the flammable ice mining in the deeo sea of the South China Sea.Subsequently,the status of on-site test mining of combustible ice deposits was presented.Finally,combined with the status of combustible ice mining at home and abroad,the mining situation of combustible ice mines is summarized,and some suggestions are put forward,pointing out the research direction of combustible ice in the future.
