1. An apparatus for feeding gas-containing well production fluids into a downhole gas separator system, the apparatus comprising:
a feed cylinder assembly separated vertically into an upper chamber and a lower chamber; a collecting tube extending into the upper chamber and the lower chamber;
wherein the upper and lower chambers are partially isolated from each other by an annular ring, disposed between an outer wall of the feed cylinder assembly and the collecting tube, whereby a partial barrier is formed to control the vertical flow between the upper chamber and the lower chamber;
an upper opening in the upper chamber connecting the feed cylinder assembly to the downhole gas separator system;
a lower opening in the lower chamber configured to connect the feed cylinder assembly to a supply of the gas-containing well production fluids;
an upper orifice in the collecting tube disposed in the upper chamber; and
a plurality of orifices in the collecting tube disposed in the lower chamber, wherein each of the plurality of orifices is smaller than the orifice in the collecting tube disposed in the upper chamber;
wherein the collecting tube is configured to pass a flow of the gas-containing well production fluids from the supply of the gas-containing well production fluids, into the plurality of orifices, through the upper orifice, and through the upper opening to the downhole gas separator system.
