ABSTRACT:
The invention relates to an apparatus for pumping and conditioning a drilling fluid normally utilized in the drilling, completion or workover of a subterranean oil or gas well. The apparatus includes a rotor housing encasing a rotatably supported rotor assembly and means for driving the rotor assembly. The rotor assembly is divided into first and second chambers. The first chamber has a radial acceleration passage, connected between an inlet for the drilling fluid and a peripheral portion of the chamber, and means for collecting a first component of the drilling fluid, the drill chips, which are the heaviest, and are forced to the periphery of the first chamber. The second chamber also has a radial acceleration passage which is connected between the first chamber and a peripheral portion of the second chamber and has a first pickup means stationarily mounted for collecting a second component, barite, at the periphery of the second chamber, a second pickup means stationarily mounted for collecting a third component, bentonite, intermediate the periphery and the center of the second chamber, and means for collecting a fourth component, gases, at the center of the second chamber. The barite and bentonite can then be recycled in the drilling fluid.
