OIL-GAS SEPARATOR WITH WATER DISCHARGE Russian patent published in 2009 - IPC E21B43/34 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry and can be employed for separation of well production into oil, gas and water. Separator incorporates horizontal cylinder case, dish-shaped input with centrifugal nozzle, and straightening and decantation partition in between of which package of coalescing nozzles is arranged. According to the invention two packages of coalescing nozzles are assembled successively between the straightening and decantation partitions; these packages are separated by a vertical partition dividing a source flow of gas-liquid mixture into parallel flows. For this purpose each package of coalescing nozzles possesses equal hydraulic resistance. Also one of parallel flows is capable to pass through the first package of the coalescing nozzles down the stream of gas-liquid mixture, while the other flow is capable to pass through the vertical partition and further through the successively arranged package of the coalescing nozzles.

EFFECT: upgraded efficiency of separator, and also quality of separation.
