Thermal and chemical impact on rheological-physical properties of non-Newtonian oils
E.M. AbbasovThe paper considers the impact of temperature and structure-destroying additives on rheological parameters of non-Newtonian oils. A number of specific thermal effects in physical-chemical processes on hydrocarbon fluids due to the presence of resin-asphaltene components in the structure of fluids was discovered. It was defined that rheological properties of oils in thermal treatment are largely specified by heating intensity of the system either in static or dynamic conditions. In such a case occurs a difference in the values of 0 shear stress and fluid viscosity in thermal treatment and, consequently, unconformity of final rheological parameters. It was revealed that structure-destroying polymer additives in various temperature conditions heterogeneously change the rheological properties of oil.
