Abstract RU 2439314 C1

FIELD: oil and gas industry.

SUBSTANCE: water is dispersed in oil emulsion. Waste water of the same oil deposit is used as water with oil product content of not more than 1% at temperature of 5-50°C. Dispersion is performed in oil pipeline with laminar flow pattern of oil emulsion at the point of oil pipeline after supply point of water-oil soluble demulsification agent. At dispersion the water in volume of 2-15% of volume of the prepared oil is supplied to oil emulsion at an angle of 45°±5° to the pipeline axis direction through the axes with diameter of 5-15 mm; the rest part is supplied under waste water layer.

EFFECT: increasing oil dehydration degree.
