    摘要： Methods of forming inserts for earth-boring tools include providing a material in a pattern adjacent a strip, arranging a plurality of superabrasive particles proximate the pattern, and securing at least some of the plurality of superabrasive particles to the strip. The material is configured to attract or secure the plurality of superabrasive particles. Some methods may include imparting like charges to each of a plurality of superabrasive particles, placing the plurality of superabrasive particles over a strip, and securing the superabrasive particles to the strip. In some methods, a first plurality of superabrasive particles may be placed in an array between a first strip and a second strip. A second plurality of superabrasive particles may be placed in an array between the second strip and a third strip. Methods of forming earth-boring rotary drill bits include forming an insert and securing the insert to a body of the bit.

    摘要： Downhole tools are provided with a topographical pattern, and anti-balling material is provided over the topographical pattern. The topographical pattern may be defined by at least one of a plurality of recesses extending into a surface of a body of the tool and a plurality of protrusions protruding from the surface. Downhole tools include an insert disposed within a recess in a body, and the insert comprises an anti-balling material having a composition selected to reduce accumulation of formation cuttings on the tools when the tools are used to form or service a wellbore. Downhole tools include anti-balling material disposed over a porous mass provided over the surfaces of the tools. Methods of forming downhole tools include providing anti-balling material over features on and/or in a surface of a body of a tool. Methods of repairing downhole tools include removing an insert therefrom and disposing a replacement insert therein.

    摘要： A rotary drill bit or other drilling tool for drilling or reaming through subterranean formation and comprising a body comprising a distal end and gage areas near a proximal end thereof and comprising longitudinally upward extensions of a plurality of blades or legs. A longitudinally trailing, radially inwardly extending surface is associated with at least some gage pads or legs at the longitudinally trailing ends thereof. Protective structures in the form of superabrasive elements comprising a plurality of thermally stable polycrystalline diamonds, or so-called “TSPs” (thermally stable products) are secured to a trailing surface of at least one gage pad. PDC elements may be employed in combination with the TSPs. Non-diamond structures may also be employed, in lieu of or in conjunction with diamond structures, particularly if drilling of ferrous metal casing components is contemplated.
