This is a high-efficiency item of equipment, for example for a well bottom for separating out gas from a liquid/gas mixture, based on the effects of flows of the cascade and segregated types. It consists basically of a sedimentation vessel whose lateral surface has holes in the upper portion, enclosing (i) a discharge pump, (ii) a suction pipe and (iii) the lower end of a production tubing. The vessel contains helicoidal surfaces for achieving segregated-type flow. A significant part of separation takes place above the level of the separator, in a medium in which there is a predominance of gas and the flow is in the form of a cascade.

1. A gas separator for separating out the gaseous phase from a two-phase, liquid/gas mixture, comprising:a sedimentation vessel having an upper part through which a production tubing extends into an interior of the sedimentation vessel, having an outlet in said upper part for the exit of gas that has been separated out, and having a lateral surface with an upper portion having through-holes therein so as to define a perforated tube; wherein in use said sedimentation vessel contains liquid in a lower part thereof up to a level varying within a selected band below the holes in said perforated tube, and contains predominantly gas in said upper portion, above the level of the liquid; a discharge pump operatively coupled to the production tubing; and level control means for keeping the level of the liquid inside the sedimentation vessel within said selected band.
