Annotation:

Rheological properties of oil during its transportation with intense sedimentation of asphalt-resin-paraffin deposition depending on resinous components content are studied. The results of the experimental studies of low-paraffinic and high-paraffinic oils show that the presence of asphaltenes and resins dispersed system in the oil can cause depression effects. According to the obtained results, it was determined that asphalt-resinous components are natural depressants that reduce paraffin crystallization temperature depending on the type of oil. Difron 4201 and BAF-1 were used as additives. It has been found that the greatest decrease of oil viscosity is observed in the presence of BAF-1 additive.
