Abstract
The paper presents the results of experimental studies of the flow of stabilized water-oil emulsions prepared from oil and formation water from the wells of the West Kochevne field, as well as with the presence of chrysotile and aerosil in cylindrical and flat capillaries (in the crack patterns). The effect of dynamic blocking has been discovered, which consists in the fact that in sections of capillaries and in a model of cracks, with a constant pressure drop, the flow of reverse oil-water emulsions stops with time. An increase in the content of isotropic and anisotropic particles led to an increase in the viscosity of the emulsion and a decrease in the time of onset of dynamic blocking. With the same percentage of particles in emulsions containing chrysotile, the time of onset of blocking and the volume of leaked emulsion before blocking is an order of magnitude less than that of emulsions containing aerosil. However, in this case, the viscosity of the emulsion with aerosil is even higher than that of a similar emulsion with chrysotile.
