- Аннотация: A series of experiments has been carried out in order to construct a master curve generalizing the combined impact of temperature and low viscosity additives on the viscosity of heavy crude oil. The goal was to establish the temperature–diluent concentration relationship to achieve a defined limit of heavy crude oil viscosity suitable for tube transportation. The ultimate viscosity limit was assumed to be 0.2–0.4 Pa·s. Three different industrially acceptable diluents (light oil, light gas oil, and spindle oil) were used for mixing with heavy oil. The viscosities of the mixtures were measured across the whole concentration range at temperatures from –20 to 50 °C. The experimental temperature and concentration dependencies of the mixture viscosity were described by corresponding equations. The data enabled to construct master curves for the determination of temperature– concentration relationships for the suitable viscosity level. The proposed approach can be applied to different heavy crude oil–diluent mixtures.
