重质油沥青质致粘机理研究进展

Research progress on viscosity-mechanism from asphaltenes of heavy oil

在总结沥青质元素、结构组成特点的基础上论述了沥青质含量,物理、化学特性与重质油粘度的关系。针对沥青质致粘机理的研究主要集中在沥青质含量、自聚集特性对粘度的影响上,而对其粘度变化的微观机理研究不足。为有效彻底提高重质油开采率,最主要是确定沥青质致粘的微观机理。

On the basis of summarizing the composition feature of element and chemical structure,this paper dissert the relation between heavy oil viscosity and asphaltenes including its nature and content. Recently,a majority of attention has been drawn to effect of content and nature,while micro mechanism research on viscosity is insufficient. At present,to effectively improve the heavy oil recovery rate,the most important is to determine micro-mechanism of asphaltene adhesion.
