Influence of Structure Forming Components on The Viscosity of Oils

Abstract

In the oil industry almost all flow models have viscosity as an intrinsic variable. Many flow behaviours will be affected by the oil viscosity. In this work model oil systems were used to study the influence of paraffin wax and asphaltenes on the viscosity of oils. In these systems the content of paraffin wax varied in the range of 3.2–8%, and asphaltenes in the range of 1.2–5.2%. It was found that the viscosity of light oils changes slightly with increasing the content of asphaltenes or paraffin wax . It was also found that the viscosity of heavy oils increases with asphaltenes content growth and decreases almost twice with the increase of paraffin wax content.
