Static separator sub

Patent ·
OSTI ID:6109864
;

This patent describes an apparatus for use in the drilling of a well with a drill bit supported by an elongated drill string having a bore through which a stream of drilling mud circulates to remove cuttings of the drill bit. The apparatus consists of: a barrel defining a central opening therethrough and having an upper end connectable to the drill string, a lower end connectable to the drill bit, the upper and lower ends in communication with the central opening, and further defining a substantially transverse hole therethrough interconnecting the central opening with a well annulus; and a cyclone separator assembly removably and fixedly positioned in the central opening in the barrel, such that an annular flow passage is defined between an outer surface of the cyclone separator assembly and an inner surface of the barrel, the cyclone separator assembly comprising: passageway means for interconnecting the annular flow passage with an upper portion of the barrel central opening; cyclone separator means; cyclone inlet means for interconnecting the annular flow passage with a lower portion of the cyclone separator means; first conduit means for directing less dense fluid downwardly into a lower portion of the barrel central opening; and second conduit means for directing more dense fluid upwardly through the cyclone separator means and having an outlet defining an operating position adjacent the barrel transverse hole.
