发明名称 Drill bit with asymmetric gage pad configuration
摘要 A drill bit for drilling a borehole in earthen formations. In an embodiment, the bit comprises a bit body having a bit axis and a bit face. In addition, the bit comprises a pin end extending from the bit body opposite the bit face. Further, the bit comprises a plurality of gage pads extending from the bit body, wherein each gage pad includes a radially outer gage-facing surface. The gage-facing surfaces of the plurality of gage pads define a gage pad circumference that is centered relative to a gage pad axis, the gage pad axis being substantially parallel to the bit axis and offset from the bit axis.
