The effect of the integrated action of low-frequency acoustic treatment, demulsifiers and the temperature factor on the stability and structural-mechanical properties of oil-water emulsions of paraffin low-resin oil from the Ignyalinskoye deposit is investigated. After low-frequency acoustic treatment of emulsions, water phase droplets are dispersed, and their number increases. Acoustic processing and introduction of demulsifier do not lead to the destruction of oil-water emulsions (10 mass %) stabilizing them due to an increase in the fragmentation of the dispersed phase. The integrated action is an effective method of the destruction of 50 mass % emulsions. After integrated processing, the size of the droplets of disperse phase in oil systems increases. Acoustic treatment of oil, oil-water emulsions (10 and 50 mass %) is accompanied by a quantitative increase in resin-asphaltene components. However, significant changes are observed only in the structural-group composition of asphaltenes.
