Patent number: 6321862Abstract: A rotary drag bit suitable for directional drilling. The bit includes a bit body from which extend radially-oriented blades carrying PDC cutters. The blades extend to primary gage pads, above which secondary gage pads are either longitudinally spaced or rotationally spaced, or both, defining a gap or discontinuity between the primary and secondary gage pads through which drilling fluid from adjacent junk slots may communicate laterally or circumferentially. Longitudinally leading edges of the secondary gage pads carry cutters for smoothing the sidewall of the borehole. The cutters are preferably configured and oriented so as to provide a relatively aggressive cutting edge to the formation in both longitudinal and rotational directions of bit movement, the cutting edges lying adjacent cutting surfaces preferably disposed at negative rake angles to the formation material of the borehole wall for enhanced durability.Type: GrantFiled: August 5, 1998Date of Patent: November 27, 2001Assignee: Baker Hughes IncorporatedInventors: Christopher C. Beuershausen, Robert J. Costo, Jr., Danny E. Scott, Rudolf C. O. Pessier, Roland Illerhaus, Mark W. Dykstra, James A. Norris, Michael P. Ohanian, John R. Spaar

Patent number: 6298930Abstract: A rotary drag bit including exterior features to control the depth of cut by cutters mounted thereon, so as to control the volume of formation material cut per bit rotation as well as the torque experienced by the bit and an associated bottomhole assembly. The exterior features preferably precede, taken in the direction of bit rotation, cutters with which they are associated, and provide sufficient bearing area so as to support the bit against the bottom of the borehole under weight on bit without exceeding the compressive strength of the formation rock. The exterior features may be oriented and configured to function optimally at a predicted rate of penetration, or range of rates, at which the bit may be operated, such rate or rates being further optionally maximized in softer formations in light of the ability of the bit to hydraulically clear a maximum volume of formation cuttings to prevent so-called bit balling.Type: GrantFiled: August 26, 1999Date of Patent: October 9, 2001Assignee: Baker Hughes IncorporatedInventors: L.

Patent number: 6173797Abstract: A rotary drill bit suitable for directional drilling. The bit includes a bit body from which extend legs carrying rotatable cutters. The body carries primary gage pads, above which secondary gage pads may be either longitudinally spaced or rotationally spaced, or both. Longitudinally leading edges of the gage pads may carry cutting structure for smoothing the sidewall of the borehole. Cutting structure may likewise be disposed on the trailing ends of the gage pads to provide an up-drill capability to facilitate removal of the bit from the borehole. The gage pads provide enhanced bit stability and reduced side cutting tendencies, as well as reducing lateral loading on the rotatable cutters and associated bearing structure and seals. The invention also has utility in bits not specifically designed for directional drilling.Type: GrantFiled: August 24, 1998Date of Patent: January 16, 2001Assignee: Baker Hughes IncorporatedInventors: Mark W. Dykstra, James A. Norris, Christopher C. Beuershausen, Rudolf C. O. Pessier
