水合物生成诱导期研究进展

水合物生成诱导期是用于表征水合物生成过程的重要参数，其研究对于水合物风险控制和水合物技术应用具有重要意义。本文从研究方法、水合物客体分子类型、研究内容和诱导期分布等4个方面总结回顾了国内外近期开展的水合物生成诱导期研究概况，表明其主要围绕诱导期定性影响因素的分析和诱导期定量表征模型的建立两方面展开。介绍了诱导期的主要定性影响因素及其对诱导期的影响规律，阐述了不同类型诱导期定量表征模型的建立过程及其适用范围。结果说明，目前对于水合物生成诱导期定性影响因素的分析研究系统性不强，需要从微观角度对水合物生成及成核机理本质展开进一步研究，而所建立的诱导期定量表征模型也大都只适用于特定条件下的水合物生成诱导期预测。

Research progress of hydrate formation induction time

The induction time of hydrate formation is an important parameter for the characterization of hydrate formation process, the research of which is of great significance for controlling of hydrate risk and application of hydrate technology. In this paper, the researches of hydrate formation induction time in recent years were reviewed from four aspects including the research methods, hydrate guest gas types, research contents and the induction time distribution. The results showed that it mainly revolved around two aspects including the analysis of qualitative influencing factors and the establishment of quantitative characterization models. The main qualitative factors influencing the induction time and their influence on the induction time were summarized. The establishment process and applicable scope of the quantitative characterization models were analyzed. Overall, the research and analysis of qualitative influencing factors of hydrate formation induction time were relatively unsystematic and a further study on hydrate formation and nucleation mechanism from the micro perspective was needed, while the existing quantitative characterization models were only applicable for the prediction of induction time in specific conditions. At last, the future research suggestions for hydrate formation induction time were proposed.
