    摘要： Methods of attaching cutting elements to earth-boring tools, comprising abutting a portion of a cutting element against at least one surface of an earth-boring tool with a braze material disposed therebetween; and brazing the cutting element to the earth-boring tool by applying high-frequency vibrations to cause the braze material to become flowable. Methods of securing cutting elements to earth-boring tools may comprise at least partially coating a cutting element with a braze material. The cutting element may be at least partially disposed in a pocket formed in a body of an earth-boring tool with the braze material adjacent surfaces defining the pocket. The cutting element and the braze material may be ultrasonically torsionally oscillated to braze the cutting element within the pocket.

    摘要： Casing shoes comprise a nose portion having an inner profile and an outer profile. At least one cutting structure is on the outer profile. A stem section extends longitudinally from the nose portion. At least one of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure is disposed within the stem section. Methods of installing sections of casing within wellbores comprise advancing the at least one section of casing into contact with subterranean formation material with a casing shoe attached thereto. At least one of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure is carried within the casing shoe into the wellbore. The wellbore is drilled or reamed using at least one cutting structure on the casing shoe as the at least one section of casing is advanced into the wellbore.

    摘要： Drill bits and methods of measuring drill bit conditions are disclosed. A drill bit for drilling a subterranean formation comprises a bit bearing at least one cutting element and adapted for coupling to a drill string. The drill bit may also comprise a chamber formed within the bit and configured for maintaining a pressure substantially near a surface atmospheric pressure while drilling the subterranean formation. In addition, the drill bit may comprise at least one optical sensor disposed in the chamber and configured for sensing at least one physical parameter exhibited by the drill bit while drilling a subterranean formation.
