Influence of magnetic field and reagents on structural and mechanical properties of high-resinity emulsion oils

Technological problems arising in the pipeline system during oil transportation are diverse and complex.Eliminating the problems arising from the transportation of high-viscosity emulsion oil through pipelines is one of the important issues of oil production industry.The effects of the amount of bound water, temperature, magnetic field, nanoparticles and surfactants on the viscosity of high-viscosity tar emulsion oils were studied.Significant change of emulsion viscosity under the action of magnetic field is observed in emulsions containing Fe 2+ /Fe 3+ ions and with higher water content.The effect of magnetic field on emulsions containing Fe 2+ /Fe 3+ ions and magnetic Fe3O4 nanoparticles is differentiated.The addition of Fe 2+ /Fe 3+ ions in the form of aqueous solutions of FeCl36H2O and (NH4)2FeSO46H2O salts to the emulsion composition leads to an increase in the viscosity of the emulsion and enhances the effect of magnetic field on the oil emulsion.When magnetic Fe3O4 nanoparticles are added to the emulsion, the viscosity of the emulsion decreases.At the content of 0.01 % of nanoparticles in the emulsion, a decrease in viscosity by 23.7 % is observed.The action of magnetic field on the emulsion containing magnetic nanoparticles contributes to a significant increase in the viscosity of the emulsion.Joint action of magnetic nanoparticles Fe3O4 and reagent D5-18 on the emulsion reduces the viscosity of the emulsion by more than 90.0 %.The combined effect of magnetic field and reagents (D5-18, PT-Y, LLP-11002) on the oil emulsion significantly reduces the viscosity of the emulsion.
