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.
As the key to achieving the hydrate risk control, the plugging regulation of hydrate in multi-phase system has always been the focus of the mobile security industry.In this paper, based on the experimental research and theoretical analysis of many researchers, some experimental devices and experimental methods are summarized, Oil-based systems, water-based systems and partially dispersed systems and other multi-phase flow system of hydrate plugging rules, and make recommendations for the follow-up study.This paper points out that different systems hydrate growth and plugging mechanism is different, oil-based block system The tube was mainly controlled by the mechanism of aggregation, wall adhesion and implantation. The water-based system was mainly controlled by the bed mechanism and the plugging trend was the lowest. The plug-tube of partial dispersion system was mainly controlled by membrane growth mechanism with the highest tendency of plugging. It is suggested that the next work can be carried out around the following aspects: theoretical modeling of wall adhesion and implantation of oil-based system, establishment of hydrate growth model of water-based system, quantitative characterization of free water in partial dispersion and considering different multiphase flow patterns The impact of plugging rules.
