METHOD OF SEPARATION OF WATER-GAS-OIL MIXTURE Russian patent published in 2004 - IPC

FIELD: oil producing industry; methods of transportation and separation of products of oil wells. SUBSTANCE: proposed method includes motion of water-gas-oil mixture in laminar mode, preliminary lamination of mixture into phases, separation of flow core into group of autonomous flows and separation of each flow of group into phases followed by blending them in common flow. Each phase of mixture is additionally subjected to separation into group of autonomous flows after preliminary lamination. Autonomous flows move upward in parallel relative to each other in rows at angle of 0.3-0.5 deg. to horizontal axis at contact of oil and gas phases of autonomous flows with hydrophilic surfaces over entire length and at contact of aqueous phase with hydrophobic surface. Blending the aqueous phase of autonomous flows in common flow is effected simultaneously and that of oil and gas phases is effected stepwise by rows. EFFECT: improved quality of separation due to reduced content of water in oil by 2.4 times and content of oil in water by 1.2-1.3 times. 2 tbl
