The article presents the results of investigations of oil samples from various deposits. The samples contain asphaltenes, resins and paraffins in different concentrations. It is established that all oil samples are non-Newtonian fluids and they have pseudoplastic properties. Due to the results of experiments, which were carried out by the method of rotational viscosimetry, size of complex structural units of oils at various sliding velocities was calculated.
