Research On The Rheological Property Of Waxy Crude Oil

On the basis of introduction of rheological property and measuring method of waxy crude oil, the characters of rheological property, rheological type, viscosity-temperature curve and thixotropic property are discussed in this article. To the measurement of rheological property, it mainly researches the theory and method of coaxial cylinder viscometer, tubule and ultrasonic wave vibration. At the same time, integrate the theory of rheological property and measurement to research the heat treating property of Nanliang, Wuqi and other six species of Changqing crude oil by experiment. The result indicates that, crude oil from different areas are different in their physical properties, but they are similar in rheological laws, such as, the law of rheological property as the temperature shift, thixotropic property and yield property.
