Abstract
A stabilizer for use with a string of single tube or dual concentric drill pipe above a bit having analogous tubular members adapted for fluid tight interconnection with the pipes of said string to provide a conduit for drilling fluid. A stabilizer means encircles the stabilizer body and is adapted to contact the hole wall. The stabilizer means includes a sleeve bearing mounted to rotate with respect to the stabilizer body and a stabilizer sleeve mounted stationary on the sleeve bearing. A port means in the stabilizer body provides fluid communication between the drilling fluid conduit and the stabilizer sleeve and/or thrust bearing. An exit port means in the lower end of the stabilizer means provides fluid communication between the stabilizer sleeve bearing and the outside of the stabilizer.
