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 (3) whose lateral surface has holes in the upper portion, enclosing (i) a discharge pump (12), (ii) a suction pipe (6) and (iii) the lower end of a production tubing (22). The vessel (3) contains helicoidal surfaces (23, 24 and 24') for achieving segregated-type flow. A significant part of separation takes place above the level (16) of the separator, in a medium in which there is a predominance of gas and the flow is in the form of a cascade.
