摘要
鉴于低温下压力对含蜡原油的流变性具有较大影响,为分析与完善压力条件下含蜡原油的流变规律,对国内外在高压条件下含蜡原油流变性的相关研究成果进行系统归纳评述,具体包括压力对含蜡原油的屈服、黏度、析蜡点和触变等流变性质的影响,阐述了含蜡原油在压力作用下各种流变性质的微观机理和这些流变性质在压力下的不同实验研究方法及其优缺点.对目前高压条件下含蜡原油性质、微观机理和测量方法等进行总结,为今后深入展开相关研究提供必要的参考.
Abstract
In view of the great influence of pressure on the rheological property of waxy crude oil at low temperature,the rheological law of waxy crude oil under pressure condition was analyzed.The relevant research results on the rheological properties of waxy crude oil under high pressure at home and abroad were systematically summarized and reviewed,specifically including the effect of pressure on the rheological properties of waxy crude oil,such as yield,viscosity,thixotropic viscoelastic and wax extraction point,and the microscopic mechanism of various rheological properties of waxy crude oil under pressure,and the different experimental research methods of these rheological properties under pressure,and their advantages and disadvantages were described.The properties,microscopic mechanism and measurement methods of waxy crude oil under high pressure were summarized,providing necessary reference for further research.
