摘　　要：简要介绍了2011年7月在英国爱丁堡召开的第七届国际天然气水合物大会概况。对会议中5个大会特邀主题报告给予介绍或评述。Thomas介绍了亨弗利.戴维对科学发现的追求和应用,后者在实验室发现了气水合物。Ripmeeste总结了实验模拟中对气水合物客体与载体相互作用、水合物形成和分解过程的认识和成果。Suess指出过去25年间人们对海洋天然气水合物的研究经历了从"避免策略到旨在获取"、"能源开发和二氧化碳储存兼顾"、"追求储量到记录环境变化"3个阶段。Kurihara总结了日本多年的研发结果,包括数字模拟研究、对甲烷储层的分类和产气能力的评估、天然气生产方法等,讨论了商业发展甲烷水合物的可行性和挑战。Sloan介绍了管道安全复杂体系的4种概念性端元类型,并指出风险管理策略比防治更为经济,是未来防止水合物堵塞的重要工具。This paper provided brief information about the 7th International Conference on Gas Hydrate （7th ICGH） held at the Edin- burgh, United Kingdom, from 17-21 July 2011. Prof. Thomas F.R. talked about how the famous scientist David devoted himself to scientific discovery and application, and how he found gas hydrates in the chemical laboratory 200 years ago. Canadian Prof. Ripmeeste introduced the results dealing with experimental simulation study on guest gas hydrate and the interaction process of hydrate formation and decomposition. He pointed out that the study on the decomposition processes in different scales became a challenge. Prof. Suess summarized three study stages in the last 25 years： ＂from a policy of avoiding gas hydrate to emphasizing deliberate drilling for it＂, ＂from exploiting gas hydrates as energy to considering exchange of CO2 for CH4 hydrates＂, ＂from pursuing methane-hydrate reserves to documenting release of methane from destabilization in marginal seas＂. Kurihara from Waseda University, Japan, introducedthe results of the past and ongoing research and development, including methods of digital simulation, classification of methane gas reservoir, and case studies; and he discussed the feasibility of commercial development and the challenges of methane hydrate. Sloan described four conceptual pictures of hydrate blockages, and suggested that two challenges in the future： interactions between flow as- surance areas, and the flow assurance concepts are illustrated beyond the pipeline, to a case of deepwater well blowout containment.
