本文介绍了改善蜡质油流变性能常用的醋酸乙烯酯（EVA）共聚物对蜡质油水包乳液体系中水合环戊烷形成的影响。所研究的蜡含量对水合物的形成有负面影响，延长了水合物的诱导时间。此外，EVA共聚物通过与油水界面附近的蜡分子的共结晶作用，延长了水合环戊烷的诱导时间。
In this paper, the effect of the ethylene vinyl acetate (EVA) copolymer, commonly used in improving rheological behavior of waxy oil, is introduced to investigate its effect on the formation of cyclopentane hydrate in a water-in-waxy oil emulsion system. The wax content studied shows a negative effect on the formation of hydrate by elongating its induction time. Besides, the EVA copolymer is found to elongate the induction time of cyclopentane hydrate through the cocrystallization effect with wax molecules adjacent to the oil-water interface.
