Viscoelastic properties of waxy crude oil [PDF]
Journal of Central South University of Technology, 2007 Waxy crude oil usually represents viscoelastic property when temperature is below its wax appearance temperature (WAT). The more the waxy crystals precipitated in crude oil, the stronger the structure and the viscoclasticity formed by waxy crystals.

Viscoelastic-thixotropic properties of gelled waxy crude oil
You-qi chuyun, 2020 The earlier thixotropic model of waxy crude oil was basically a viscoplastic model, in which the contribution of viscoelasticity was not considered, and the influence of viscoelasticity was not taken into account in the numerical simulation of pipeline ...

Influence laws of crude oil composition on wax precipitation characteristics of waxy crude oil
You-qi chuyun, 2020 Accurate prediction on wax precipitation characteristics is very important to seize the right time to clean and prevent from wax. Three series of simulated crude oils were prepared on the basis of crude oil composition and its analysis. The composition of the oil sample and the carbon number distribution of the wax composition were analyzed with high ...

Study on influence of flow rates on voids in waxy crude oil subjected to dynamic and static cooling [PDF]
Journal of Mechanical Engineering and Sciences, 2015 The assumption of constant yield stress in the conventional restart pressure equation neglects the effects of thermal shrinkage and gas voids formation, which in turn resulted in an over-designed production piping systems.

Characteristic temperatures of waxy crude oils [PDF]
Petroleum Science, 2007 Gel point or pour point is widely used to evaluate the low temperature flowability of crude oil. However, it is not adequate to describe the gelling properties of waxy crude oils under flow conditions with gel point or pour point, since the rheological behavior of crude oils is dependent on shear history.
