DOUBLE GAS SEPARATOR (OPTIONS) Russian patent published in 2022 - IPC F04D13/10 

FIELD: oilfield equipment.

SUBSTANCE: inventions group relates to oilfield equipment, in particular to gas separators, and can be used for oil production, complicated by a high gas ratio. The dual gas separator contains lower and upper centrifugal gas separators with outlets for removing gas into the annulus and the inlet module. The upper gas separator is made with a smaller diameter than the lower gas separator. Gas separator outlets are rotated 180 degrees relative to each other. Each outlet is equipped with a branch oriented along the gas separator and acting as a bypass. In another version, the outlets of the lower and upper gas separators are located inside the coaxially mounted casing and are separated from each other by longitudinal partitions. The casing is bounded from below by a blind transverse partition.

EFFECT: ensuring efficient, reliable operation of the gas separator when producing well fluid with a high gas content.
