    摘要: A stabilizer (1) especially adapted for use with an drill string having an eccentric drilling element, such as a bi-center bit. The stabilizer (1) has a pair of circumferentially displaced blades (18) that lie in a common circumferential plane and extend from a rotatable sleeve (20) supported on the stabilizer body (50) , as well as a stationary blade (17). The rotating blades (18) are aligned with the stationary blade (17) when in a first circumferential orientation and are disposed so that the mid-point between the rotating blades (18) is located opposite the stationary blade (17), thereby providing full-gauge stabilization, when the rotating blades (18) are in a second circumferential orientation. A magnetic system (60) senses the circumferential orientation of the rotating blades (18) and transmits the information to the surface via mud pulse telemetry. A piston (141) actuated by the drilling mud locks the rotating blades (18) into the active and inactive positions. A brake shoe (59) located on the distal end of each rotating blade (18) provides contact with the walls of the borehole and serves as a support pad (59) for a formation sensor (45).

    摘要: A drilling assembly includes an eccentric adjustable diameter blade stabilizer having a housing (!2) with a fixed stabilizer blade (30) and a pair of adjustable stabilizer blades (40,42). The adjustable stabilizer blades (40,42) are housed within openings (60,62) in the stabilizer housing (12) and have inclined surfaces (88,90) which engages ramps (78,80) on the housing (12) for camming the blades (40,42) radially upon their movement axially. The adjustable blades (40,42) are operatively connected to an extender piston (104) on one end for extending the blades and a return spring (110) at the other end for contracting the blades. The eccentric stabilizer also includes one or more flow tubes (44) through which drilling fluids pass that apply a differential pressure across the stabilizer housing (12) to actuate the extender pistons (104) to move the stabilizer blades (40,42) axially upstream to their extended position. The eccentric stabilizer is mounted on a bi-center (202) which has a eccentric reamer (208) section and a pilot bit (206).
