IMPROVING DRILL BIT STABILITY USING TRACK-SET DEPTH OF CUT CONTROL ELEMENTS |
| 摘要 |
A drill bit using track-set depth of cut control elements to provide improved stability is disclosed. A drill bit for drilling a wellbore includes a bit body with a rotational axis extending therethrough. The drill bit further includes a plurality of blades disposed on exterior portions of the bit body. The drill bit includes a first group of track set depth of cut controllers (DOCCs) disposed on exterior portions of a first set of the plurality of blades. The first group of track set DOCCs configured to be placed within a first radial swath of a bit face of the drill bit and configured to provide a first critical depth of cut (CDOC). |

1. A drill bit designed for drilling a wellbore, comprising:
a bit body with a rotational axis extending therethrough; a plurality of blades disposed on exterior portions of the bit body; and a first group of track set depth of cut controllers (DOCCs) disposed on exterior portions of a first set of the plurality of blades, the first group of track set DOCCs configured to:
be placed within a first radial swath of a bit face of the drill bit such that at least two of the track set DOCCs in the first group are located at the same radial position with respect to the rotational axis; andprovide a first critical depth of cut (CDOC). |
