含蜡原油中的蜡晶形态

Study on Morphology of Crystals

含蜡原油中蜡的形态结构对其流变性有着重要影响。叙述了国内外学者利用光学显微镜和散射技术对蜡晶形态的研究。介绍了蜡晶形态研究过程中引入低温技术的处理方法与结果 ,利用低温技术使蜡晶形态保持样品最初 (未冷冻时 )的质地特征 ,并用电子显微镜研究了静态及动态条件下的蜡晶形态 ,指出结晶核为薄片状 ,厚度与分子大小相当 ,它们的进一步发展依赖于结晶条件。

The morphology of crystals of crude oil is one of the most important factors for the oil's rheology.The researches on the morphology of crystals are summarized briefly,and the work on morphology using cryotecnique by Moussa is emphasized.It is pointed out that more researches are needed to develop a mechanistic rheological model of the crude oil.
