The destruction of water-oil emulsions.
The destruction of stable oil-water emulsions as containing “gel” and do not contain, and the separation of the water phase is performed using the combined wave action (ultrasonic, magnetic, and electromagnetic) together with the additives.
Water-oil emulsion is a mixture of two mutually insoluble liquids, one of these fluids finely dispersed in the other.
Water-oil emulsions are of three types:
emulsion of the first kind (direct emulsions) – oil dispersed phase, water dispersed medium;
– emulsion of the second kind (invert emulsion) – dispersion medium of oil, the disperse phase water.
– multiple emulsion is a system where a relatively large drops of water may contain small globules of oil, or large drops of oil are small globules of water. The disperse phase is itself an emulsion, and can be both direct and inverse type.
Formation of emulsions may occur in bottom-hole zone of the well, the wellbore and in surface equipment.
The resulting emulsion without separation of its components components cannot be used in the future, and therefore require destruction.
The destruction of water-oil emulsions by conventional methods (centrifugation, thermal effects, settling, filtration, electric effects, the effects of magnetic fields, etc.) is costly and not always effective.
Method of destruction of oil-water emulsions, including steady as containing “gel” and do not contain, – using combined wave action (ultrasonic, magnetic, and electromagnetic) together with additives is more effective.
