摘要： In general, in one aspect, embodiments relate to a drill bit, that includes a bit body, a plurality of cutters secured to the bit body, an axial reciprocating assembly, a lateral reciprocating assembly, and a sliding interface that includes a first contact surface and a second contact surface in direct sliding engagement with the first contact surface inside the bit body, such that an exposure of the first borehole engagement member varies with an exposure of the second borehole engagement member.

摘要： The disclosure provides a drill bit including a bit body and a blade extending form the bit body. The blade includes a first element protruding from a surface of the blade and a second element protruding from the surface of the blade. The first element and the second element are each configured to extend or retract relative to the surface of the blade and are coupled to each other such that when the second element retracts relative to the surface of the blade, the first element extends relative to the surface of the blade. The first element is disposed within a first pocket formed in the surface of the blade, and the second element is disposed within a second pocket formed in the surface of the blade. A communication channel is formed between the first pocket and the second pocket.

摘要： A drill bit has a plurality of cutters secured to the bit body, including a gauge cutter defining a gauge diameter of the drill bit. A reciprocating gauge assembly on the bit comprises a cavity defined in the bit body, a piston reciprocably disposed in the cavity, a wear element on an outwardly facing end of the piston, a piston retainer for moveably retaining the piston in the cavity, and a spring biasing the piston outwardly to a neutral position of the wear element with respect to the gauge diameter. The wear element and piston may be urged inwardly in response to an applied load at the drill bit gauge pad, increasing the lateral depth of cut and thereby controlling the aggressiveness of the bit in response to the load.

摘要： A depth of cut control (DOCC) assembly includes a DOCC element positioned in a retainer pocket along a drill bit blade to limit a depth of cut of one or more fixed cutters. A retention member initially retains the DOCC element within the retainer pocket at a first exposure position. The retention member is configured to release the DOCC element downhole to allow one-way movement of the DOCC element to a second exposure position.

摘要： A variety of methods, systems, and apparatus are disclosed, including, in one embodiment, a drill bit, comprising: a bit body defining a rotational axis and having a plurality of cutter pockets formed thereon, each cutter pocket shaped to receive a respective substrate of a cutter; wherein each cutter pocket has an inner profile that defines an area of increased braze gap that conforms to an outer profile of the respective substrate; and a braze interface comprising a braze alloy disposed in each cutter pocket between the inner profile of the cutter pocket and the outer profile of the respective substrate, such that a thickness of the braze alloy is greater at the area of increased braze gap.
