© 2020 IOP Publishing Ltd. All rights reserved. This article is devoted to the studying of the problem of the resin and asphaltene deposits formation in the process of oil production and transportation using the example of high-viscosity oil from the Ashalchinskoe field. The chemical method for the prevention and removal of ARPD, connected with the use of phosphorylated alkylphenols is considered in detail. Extraction of asphaltenes was carried out by selective dilution of the oil sample following by washing in Soxhlet apparatus. Hydrocarbon structure of asphaltenes was studied by the method of IR-spectroscopy on the spectrometer PerkinElmer. Paramagnetic characteristics of asphaltenes were analyzed by EPR method. Rheological properties of oil emulsion were studied by viscosimetry method using rotational viscometer One Touch Lamy Rheology. The graphs that indicate the dependence of the viscosity of oil emulsions on applied shear stress were plotted. The method of the "cold rod" was used to evaluate the inhibitory effect of the new organic compound.
