The research of structure and properties of high-viscosity crude oils under the effect of oil-displacing compositions in laboratory environment

Abstract

The authors have studied the influence of surface-active substances and components of oil-displacing compositions on properties and composition of high-viscosity crude oils as a result of thermostating of oil-composition (oil-water) systems in laboratory environment. It was shown that presence of composition in the system results in decreasing the content of solid paraffin hydrocarbons, in increasing abundance ratio of aromatic structures and resinous-asphaltic components in oils.
