FIELD: oil and gas industry.

SUBSTANCE: multiphase separation system comprises a distribution line made with a configuration which provides the possibility of multiphase fluid supply into supply lines in separation system, wherein the supply lines consist of a top line, a middle line and a bottom line; and adjustable volume. The top line is made with a configuration which provides the possibility of directing the first flow comprising oil into the section of adjustable volume intended for oil. The middle line is made with a configuration which provides the possibility of directing the second flow comprising water-oil emulsion into section of adjustable volume intended for water-oil emulsion. The bottom line is made with a configuration which provides the possibility of directing the third flow comprising water into section of adjustable volume inteded for water. Adjustable volume is made with a configuration which provides the possibility of regulating fluid flow velocity at the output, wherein the section intended for oil, the section intended for water and the section intended for water-oil emulsion are connected each at different heights of adjustable volume.

EFFECT: increased amount of oil and gas extracted from underwater wells at great depth.
