Forecasting the viscosity properties of water-oil systems

Abstract

In article possibilities of predicting the viscosity of stable multicomponent water-oil systems in practice, when it is impossible, for a number of reasons, to obtain their experimental values, are considered. A predictive model is proposed to describe the change in the viscosity properties of various oil-water emulsions depending on the degree of water saturation. It is shown that the proposed formula allows to determine the effective viscosity of water-oil systems in the entire range of variation of the velocity gradient in the absence of experimental data and is acceptable for engineering practice. Keywords: viscosity; water-oil emulsions; matematical description; water saturation degree; heterogeneous systems.

Development of the diasgnostic method for determination of density of «water-oil-sand» type mixtures

“…However, the solution to this problem requires consideration of many important factors, and often the proposed solutions do not justify themselves. For example, in the analysis of multicomponent systems, the use of linear dependencies, which characterize the dynamics of change of only one of the constituent elements, is considered unacceptable [5]. The studies show that the determination of density by additivity rule requires numerous analyzes in order to study the quantitative and qualitative composition of the granular element that is part of this mixture, which is accompanied by a number of material and time costs [6].…”
