| Abstract | The drilling assembly includes an eccentric adjustable diameter blade stabilizer (30), having a housing (43) with a fixed stabilizer blade (32) an d a pair of adjustable stabilizer blades (34, 36), and a bi-center bit (20), having an eccentric reamer section (24) and a pilot bit (22), mounted on the eccentric stabilizer (30). The stabilizer (30) and bit (20) have an alignmen t mechanism (40) for aligning the fixed blade (32) with the reamer section (24 ). The alignment mechanism (40) includes an aperture (44) on the bit (20) which is aligned with an aperture (42) on the stabilizer (30) as the stabilizer (3 0) is made up on the bit (20). An alignment member (48) is received by the aligned apertures (42, 44) for maintaining the alignment. |
