Abstract
A downhole separator and method for use of the same for fluid mediums with low viscosity are disclosed. In one embodiment, the downhole separator has a housing with inlet openings that draw a fluid flow into an elongated annular separation chamber within the housing. The fluid flow advances under angular momentum imparted by a rotation of a shaft located in the housing. The shaft includes a profiled surface that imparts drag to the fluid medium and two local pressure increasing units to effect at least partial separation of the fluid medium into the following: (i) a liquid portion upwardly traversing the fluid passageway of the shaft via the inlet ports; (ii) a gaseous portion upwardly traversing the elongated annular separation chamber to the plurality of upper gaseous portion outlets; and (iii) a solid portion downwardly traversing the elongated annular separation chamber to the plurality of lower solid portion outlets.
