In the equipment operated in the oil industry, the formation of a solid layer of AWPC on the inner surface of the pipes causes the precipitation of salts and the formation of an aggressive environment, which leads to corrosion of the equipment and its rapid failure, There are many studies on the fight against paraffin deposition, Based on the results of these studies, the mechanism and conditions of paraffin deposition have been studied, and methods and measures for combating it have been developed, Nevertheless, the elimination of problems caused by paraffin deposition during the movement of highly paraffinic oils remains relevant, Therefore, the development of new physicochemical methods in the fight against ARWD is of great importance, In the article, a new method is proposed for testing paraffin deposition inhibitors, taking into account the structural and energy properties of oil,
The study of the effect of chemical reagents, magnetic and cavitation environments on the structural and rheological properties of Azerbaijani crude oil, depending on the amount of tar-asphaltenes-paraffins, was conducted.
