摘 要:油包水乳状液中水合物生长行为的差异会影响水合物的生长速率和生成量,为多相管道的安全运行和流动保障策略的制定带来挑战。本文结合国内外关于油包水乳状液中水合物生成行为的实验及理论研究成果,系统阐述了水合物生成实验研究方法及水合物生长过程常用量化指标,总结了油水体系中油相组成、含水率等因素对水合物生长行为的影响规律,分析了油包水乳状液中水合物的生长机理和量化模型的研究进展。文章指出,油包水乳状液中水合物生成方法和量化指标已较为完善,对影响因素和生长机理的认识正日趋深入。未来应进一步探明多组分复杂体系下的水合物生长动力学行为,并从微观角度深入对油水体系中水合物壳体结构及生长机理的理解,最终建立适用于实际多相管道的水合物生长速率模型。The variation of hydrate growth behaviors can affect the growth rate and formation amount of hydrates in water-oil emulsions,posing challenges to the safe operation of multiphase pipelines and the development of flow assurance strategies.In this work,the experimental methods for hydrate formation and the quantitative indexes of hydrate growth rate are systematically reviewed.The influence of key factors(e.g.,composition of oil phase and water cut) on hydrate growth behavior is summarized.In addition,the research progress on the growth mechanisms and the quantitative models of hydrate formation are deeply analyzed.Overall,the experimental methodology and quantitative indexes of hydrate growth have been well-developed,and a deeper understanding of the influencing factors and growth mechanism has been gained.In future studies,the hydrate growth behaviors under multi-component complex systems should be further explored.The understanding of hydrate shell structure and growth mechanism in water-in-oil emulsions should be deepened from the microscopic perspective.Based on all these studies,the hydrate growth rate model for actual multiphase pipelines could be established.
