The paper presents the comparative analysis of inverse emulsion rheological behavior stabilized by monoethanolamide and diethanolamide of tall oil fatty acids, which are promising reagents for petroleum engineering. Flow curves of emulsions and volume ratio of dispersed phase have been obtained. The analysis of the dependence of Herschel-Bulkley model parameters on concentration of emulsifiers has been carried out. It is proved that emulsifiers affect weakly on the rheological parameters in high water phase content emulsions, while in cut-back emulsions their impact is registered to be stronger. It has been found that rheological parameters of the emulsions stabilized by monoethanolamide throughout the range of concentration are considerably higher than the samples on the base of diethanolamide. The experimental data proved the key impact of viscosity of dispersion medium on rheological behavior of cut-back emulsions.
