Getting Viscous Additives from Heavy Oil Fraction

Annotation: To improve the viscosity and improve the rheological characteristics of the produced oil in fields with heavy, high-viscosity oil, a number of technologies are used. Heat treatment and other methods of physical exposure; dilution with light fractions of oil or various solvents, as well as the introduction of additives that regulate the viscoelastic properties of the oil. The work considers nonionic and anionic surfactants that are obtained from petroleum products. Alkyl aromatic and alkyl naphthenic-aromatic hydrocarbons in the heavy oil fraction are the most important that produce fat-soluble additives.
