Drill Bits With Controlled Exposure Of Cutters

View page
US Patent:
6779613, Aug 24, 2004
Filed:
Oct 7, 2002
Appl. No.:
10/266534
Inventors:
Mark W. Dykstra - Kingwood TX
William Heuser - The Woodlands TX
Michael L. Doster - Spring TX
Jack T. Oldham - Willis TX
Terry D. Watts - Spring TX
Daniel E. Ruff - Kingwood TX
Rodney B. Walzel - Conroe TX
Christopher C. Beuershausen - Spring TX
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 1046
US Classification:
175 57, 175428, 175431
Abstract:
A rotary drag bit and method for drilling subterranean formations including a bit body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per bit rotation, as well as to control the amount of torque experienced by the bit and an optionally associated bottomhole assembly regardless of the effective weight-on-bit. The exterior of the bit preferably includes a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute an additional weight applied to the bit against the bottom of the borehole without exceeding the compressive strength of the formation rock.
