摘　　要：含蜡原油粘弹性源于其内部的蜡结晶量与复杂的蜡晶形态及结构,但二者间的定量关系仍未建立起来。在概述含蜡原油蜡晶形态和结构的定量表征与总结粘弹性研究的基础上,进一步分析了二者间定量关系的研究现状,并指出了存在的问题与进一步的研究课题。建议在悬浮液及凝胶体系的有关理论框架下,结合大量的试验研究,利用数理统计分析方法,深入探索粘弹性与蜡晶形态及结构间的定量关系,以丰富对原油流变学微观机理的认识。The viscoelasticity of waxy crude oil originates from its internal wax crystal amount and its complex wax crystal shape and structure, but the quantitative correlation between them is not established. On the basis of quantitative characterization of waxy crude oil crystal shape and structure and summarizing its viscoelasticity, the current situation of studying the correlation between them is further analyzed, the problems existed and project of research are put forward. It is proposed that by using the theories of suspended fluids and colloidal system and in combination with large number of tests, a statistic mathematical method is used for deeply studying the quantitative correlation between the waxy crystal shape and its structure for the purpose of enriching the recognition of rheologic microscopic mechanism.
