METHOD FOR SEPARATION OF WATER-GAS-OIL MIXTURE Russian patent published in 1997 - IPC

FIELD: oil production industry. SUBSTANCE: this relates to transportation and separation of oil well products in collection, preparation and transportation of oil. Method implies moving of flow of water-gas-oil mixture in laminar mode, separating it into bundle of flows and after lamination of each flow in bundle, converging them into common flow. Subjected to separation into bundle of flows is only core of flow. Flows in bundle are moving in horizontal direction, and after their convergence - in inclined direction with counterflow bubbling by gas bubbles of chemical composition which is identical or equivalent to separated gas phase. EFFECT: high efficiency.
