【摘要】：多相体系水合物堵管规律作为实现水合物风险控制的关键,一直备受流动安全保障行业的关注.本文结合众多研究者的实验研究及理论分析,总结了部分实验装置及实验方式,概述了油基体系、水基体系及部分分散体系等多相流动体系的水合物堵管规律,并对后续研究的开展提出建议.本文指出不同体系水合物的生长及堵管机理不同,油基体系堵管主要受聚并、壁面黏附及着床等机理的控制;水基体系堵管主要受着床机理控制,堵管趋势最低;部分分散体系堵管主要受膜生长机理控制,堵管趋势最高.建议下一步工作可围绕以下几点展开:油基体系壁面黏附及着床的理论建模,水基体系水合物生长模型的建立,部分分散体系自由水的量化表征以及考虑不同多相流流型对堵管规律的影响.
[Abstract]:As the key to realize hydrate risk control, the rule of gas hydrate plugging in multiphase system has been paid more and more attention by the flow safety industry. In this paper, based on the experimental research and theoretical analysis of many researchers, some experimental devices and experimental methods are summarized, and the rules of gas hydrate plugging in oil-base, water-based and partially dispersed multiphase flow systems are summarized. And put forward suggestions for the development of follow-up research. In this paper, it is pointed out that the growth and plugging mechanism of hydrate in different systems are different, the plugging mechanism of oil-based system is mainly controlled by coalescence, wall adhesion and implantation, while the plugging mechanism of water-based system is mainly controlled by the mechanism of implantation, and the trend of plugging is the lowest. The plugging mechanism of partially dispersed system is mainly controlled by the film growth mechanism, and the plugging trend is the highest. It is suggested that further work should be carried out around the following aspects: the theoretical modeling of oil base system wall adhesion and implantation, the establishment of hydrate growth model of water-based system, Quantitative characterization of free water in partially dispersed systems and consideration of the effects of different multiphase flow patterns on pipe plugging.
