FIELD: oil and gas industry.
SUBSTANCE: invention refers to a method for prevention of accumulation of electrostatic charges in emulsions at oil production and transport using neutralising devices; at that, at oil collection stage, antistatic surface-active substance is introduced to the well; at oil treatment stage, late dosing of demulsifiers is performed.
EFFECT: prevention of generation of static electricity and accumulation of electrostatic charges of oil-water emulsion.
