摘要： In accordance with some embodiments of the present disclosure, a method of configuring a depth of cut controller (DOCC) of a drill bit comprises determining a first desired depth of cut for a first radial swath associated with a bit face of a drill bit. The first radial swath is associated with a first area of the bit face. The method further comprises identifying a first plurality of cutting elements located on the bit face that each include at least a portion located within the first radial swath. The method additionally comprises configuring a first depth of cut controller (DOCC) for placement on the bit face within the first radial swath. The first depth of cut controller is configured based on the first desired depth of cut for the first radial swath and each portion of the first plurality of cutting elements located within the first radial swath.

摘要： According to some embodiments of the present disclosure, a method of determining a critical depth of cut of a drill bit comprises selecting a radial swath associated with an area of a bit face of a drill bit.. The method further comprises identifying a plurality of cutting elements disposed on the bit face that each include at least a portion located within the radial swath. The method also comprises identifying a depth of cut controller (DOCC) disposed on the bit face and configured to control a depth of cut of the portions of the plurality of cutting elements located within the radial swath. The method additionally comprises calculating a critical depth of cut associated with the radial swath and DOCC based on a depth of cut associated with each portion of the plurality of cutting elements located within the radial swath and controlled by the DOCC.

摘要： A multi-layer downhole drilling tool designed for drilling a wellbore including a plurality of formations is disclosed. The drilling tool includes a bit body including a rotational axis extending therethrough. A plurality of blades are disposed on exterior portions of the bit body. A plurality of primary cutting elements and a plurality of back-up cutting elements are disposed on exterior portions of the plurality of blades. The back-up cutting elements are track set with corresponding primary cutting elements, and each back-up cutting element is disposed on a different blade than the corresponding primary cutting element.

摘要： According to some embodiments of the present disclosure, a method of configuring a blade of a drill bit comprises determining a first desired depth of cut for a first radial swath associated with a bit face of a drill bit. The first radial swath is associated with a first area of the bit face. The method further comprises identifying a first plurality of cutting elements located on the bit face. Each of the cutting elements includes at least a portion located within the first radial swath. The method additionally comprises configuring a first blade surface of a blade. The first blade surface is located within the first radial swath and configured based on the first desired depth of cut for the first radial swath. The blade surface is also configured based on each portion of the first plurality of cutting elements located within the first radial swath.
