Annotation:

The formation of asphalt-resin-paraffin deposits is one of the most urgent problems in the production and transportation of oil in oil fields, including those in the Perm Territory. As part of the trend towards digitalization of the oil field, it is necessary to create a mathematical model of these deposits formation, capable of predicting their spatial and temporal distribution along the length of the production string or oil gathering system. The authors of the article comprehensively studied the dynamics of deposits formation under various thermal and velocity conditions. The re-sults of the studies are presented in the form of graphs and indicate the fact that the formation of deposits is mostly affected by temperature conditions. The analysis of the obtained data showed that the greatest intensity of deposits formation occurs at high oil temperature and low speed. It is noted that when oil is heated above the crystallization onset temperature or the flow velocity increase, the effect of thermal and velocity parameters changes.
