摘　　要：为了解决天然气水合物降压分解过程中孔隙尺度精细描述的难题,开展了天然气水合物微观可视模型实验设计。实验装置设计从具备可视功能、实时监测功能、数据处理功能和临界状态判断功能入手,开展了设备初始化调试、生成与分解模拟和产气效率分析等共3个层次实验内容。实验结果表明,学生不但能够定性描述水合物微观孔隙水合物生成与分解过程,而且实现了定量计算不同时刻水合物产气效率,这为学生对水合物微观生成与降压分解规律的理解奠定了基础。实验加深了学生对海洋油气工程专业知识的理解,提升了学生解决复杂工程问题的实践能力。In order to solve the problem of fine description of pore scale during the synthesis and decomposition of natural gas hydrate, the experimental design of microscopic visual model of natural gas hydrate was carried out. The design of the experimental device starts with visual function, real-time monitoring function, data processing function and critical state judgment function, and carries out the equipment initialization debugging, synthesis and decomposition simulation and gas production efficiency analysis of three levels of experimental content. The experimental results show that students can not only qualitatively describe the process of hydrate synthesis and decomposition in microscopic pores, but also quantitatively calculate the gas production efficiency of hydrate at different moments, which lays a foundation for students to understand the law of hydrate formation and depressurization decomposition. The experiment deepens students’ understanding of the professional knowledge of offshore oil and gas engineering and improves their practical ability to solve complex engineering problems.
