Abstract: A math modelling of viscosity/temperature properties of anomalous non-Newtonian oilis of great interest, both from as the point of view of fundamental research well asoperation tasks of pipeline transportation of oil. Thermohydraulic calculations, determining the time of safe stop and starting characteristics of non-isothermal pipelines for highly paraffin and heavy oil require the use of reliable models that could accurately describe the actual flow laws in a wide range of temperatures and rates. It is in detail considered the shortcomings of existing equations for describing the flow parameters of non-Newtonian fluids, also is proposed the new rheological model and algorithm for automating the calculation of its parameters. The results of the accuracy estimation of the proposed method are compared with Balkley-Herschel equation.
