This article gives a relatively new interpretation of the characteristic phenomenon of "phase inversion" in water-oil emulsions, created on the basis of non-Newtonian oils from fields in Azerbaijan. An analysis of the results obtained showed that an increase in the water-cut threshold in these emulsions has a strong effect on their rheological characteristics and leads to noticeable microstructural changes.

The article deals with the regulation of the rheophysical properties of multicomponent mixtures on the basis of the purposeful application of a new direction in science-rheotechnology. The data of rotoviscometry once again confirmed that the sequence of mixing the constituent components of the oil-water-sand mixture directly affects the rheology of the newly formed systems. The method of changing the order of entering the constituent components shows the prospects for increasing the efficiency of the processes of extraction, collection and transport of oils and their mixtures based on the creation of new rheological methods based on the regulation of the rheophysical properties of the heterophase systems under consideration. Keywords: constituent components of the mixture; rheology; structural viscosity; anomalous index; graph-analytical method.
