摘　　要：随着天然气水合物勘查试采工作的不断深入,世界主要国家以实现水合物产业化开发为目标的科学理论研究和技术装备研发面临发展瓶颈,目前仅中国、日本、美国等几个国家仍在积极推进旨在突破上述发展瓶颈的长期水合物试采工作.日美两国自2014年就阿拉斯加长期陆域试采项目达成合作意向以来,基本完成了产气试验前的准备工作.本文在梳理总结已开展的中短期水合物试采项目及长期试采必要性的基础上,重点介绍了项目团队对试采场地的选择、地层测试井的钻探以及基于数据采集的目标储层表征,认为我国在缺少可供长期陆域试采的合适区域的情况下,可加强与俄罗斯在水合物勘查开发相关领域(尤其是长期陆域试采)的深入交流与合作.尽管我国的水合物试采工作在产气时长、日最高产气量和累计产气量等方面处于领先,但应针对钻井、完井、人工举升、地质力学、出砂、防砂等领域加强科学理论研究和关键技术攻关.With the continuous deepening of natural gas hydrate exploration and production test,the industrialization of hydrate development meets a bottleneck for the scientific theoretical research and technical equipment development in major countries of the world.At present,only a few countries such as China,Japan and the United States are still actively promoting long-term hydrate production test to break the bottleneck.Since 2014,when Japan and the United States reached an intention to cooperate on a long-term onshore production test project in Alaska,the two countries have basically completed the preparatory work before the gas production test.Based on the summary of previous short-and medium-term hydrate production test projects and necessity of long-term production test,the paper focuses on the project team's selection of test sites,drlling of formation test wells as well as characterization of target reservoirs based on data acquisition.It is suggested that China may strengthen in-depth exchanges and cooperation with Russia in the fields related to hydrate exploration and development(especially long-term onshore production test)as the absence of suitable areas for long-term onshore production test.Although China has led the way in hydrate production test in terms of gas production duration,maximum daily gas production and cumulative gas production,the scientific theoretical research and key technical development should also be strengthened in the fields of drilling,well completion,artificial lift,geomechanics and sand controlling.
