摘要 ?
相較于傳統(tǒng)的水合物生成抑制方式,，向管線中添加低劑量抑制劑的水合物風險控制策略，在深水多相集輸領域防控水合物堵塞中具有顯著的優(yōu)勢,，備受國內外學術與工業(yè)界的青睞,。阻聚劑是一種能在更為苛刻的高過冷度工況下，仍具有良好阻聚效果的低劑量抑制劑,，可保證多相混輸流體內生成的水合物以漿液呈現(xiàn)可輸送狀態(tài),。本文重點闡述了影響阻聚劑性能的關鍵因素，梳理了阻聚劑存在體系內水合物生成及流動的宏微觀特性,?？傮w而言，阻聚劑的性能受加劑量,、含水率,、礦化度,、pH、溶液乳化狀態(tài)及應用工況過冷度等綜合因素的影響,；添加阻聚劑體系的水合物漿液內水合物生成量穩(wěn)定適中,、流動性越好，油氣水混輸系統(tǒng)內發(fā)生水合物堵塞的風險越低,，其流動安全的保障可靠性越高,。基于上述研究,，本文總結了阻聚劑對水合物的作用機理,，并給出了未來深入開展阻聚劑研究的建議。

Abstract ：
Compared with the traditional method of hydrate prevention and control in the field of multiphase gathering and
transportation in deep water, the method of adding low-dose hydrate inhibitor has significant advantages. It is favored in academic
and industrial fields at home and abroad. Anti-Agglomerant (AA) is one type of the low-dose hydrate inhibitors that can still have
good performance under more severe high undercooling conditions, which can ensure that the generated hydrate in multiphase flows
can mix with the transport fluid as slurry. In this work, the indexes for evaluating the performance of anti-agglomerants and the key
influence factors are summarized. The macro and micro characteristics of hydrate formation and the flow features of hydrate slurry
in the presence of anti-agglomerants in the system are reviewed. In general, the performance of AA is affected by its dosage, water
cut, mineralization degree and pH of the fluid, the emulsification state and subcooling degree under the application conditions. The
more stable and moderate the hydrate formation amount is, the better is the fluidity of the hydrate slurry with AA addition and the
lower the risk of hydrate blockage occurring in the multiphase flow with higher reliability of ensuring its flow safety. Based on all the
research, the mechanisms of AA are summarized. Finally, suggestions for further research on anti-agglomerants in the future are given.
