Abstract
The similarity of the results of exposure to an electromagnetic field, shear stresses, pressure fluctuations, for example, on the viscosity of oil, the rate of growth of paraffin deposits, the rate of growth of Ca/Mg carbonates deposits suggests that such results are the result of the same primary changes in the colloidal components of these systems.Based on the analysis of experimental data, it is shown that the results of such impacts can be explained by the destruction of colloidal aggregates of fractal structure consisting of colloidal particles of different material composition.Due to presence of magnetic and/or electrically charged metal oxides particles in fractal aggregates it make to be possible to split aggregates into separate fragments by applying electromagnetic fields. The particles in suchstructures are interconnected by such weak forces of electric and magnetic origin that the destruction of aggregates occurs even at small values of the fluid velocity gradients corresponding to small values of shear stresses.
