Definitions

  • Drag bits having cutting elements made of an ultra hard cutting surface layer or “table” (typically made of polycrystalline diamond material or polycrystalline boron nitride material) deposited onto or otherwise bonded to a substrate are known in the art as polycrystalline diamond compact (“PDC”) bits.
  • PDC polycrystalline diamond compact
  • Cutters are conventionally attached to a drill bit or other downhole tool by a brazing process.
  • a braze material is positioned between the cutter and the cutter pocket. The material is melted and, upon subsequent solidification, bonds (attaches) the cutter in the cutter pocket.
  • Selection of braze materials depends on their respective melting temperatures, to avoid excessive thermal exposure (and thermal damage) to the diamond layer prior to the bit (and cutter) even being used in a drilling operation.
  • alloys suitable for brazing cutting elements with diamond layers thereon have been limited to only a couple of alloys which offer low enough brazing temperatures to avoid damage to the diamond layer and high enough braze strength to retain cutting elements on drill bits.
  • a cutter assembly that includes: a rolling cutter cartridge having at least two cutter cavities formed therein; at least two rotatable cutting elements having a groove formed in a side surface thereof disposed within the at least two cutter cavities, the at least two cutter cavities interfacing the grooves in the at least two rotatable cutting elements; wherein the at least two cavities and at least two rotatable cutters are spaced such that less than 0.1 inches is spaced between the at least two rotatable cutters.
  • embodiments disclosed herein relate to a downhole cutting tool, that includes: a cutting element support structure having at least one cutter assembly pocket formed therein; at least one cutter assembly disposed in the at least one cutter assembly pocket, the at least one cutter assembly including: a rolling cutter cartridge having at least two cutter cavities formed therein; and at least two rotatable cutting element disposed within the at least two cavities; and at least one retention mechanism retaining the at least two rotatable cutters in the rolling cutter cartridge.
  • FIGS. 2A-D show various views of assembly of an embodiment of a retention component used to retain multiple cutting elements.
  • FIG. 4 shows a top, cross-sectional view of an embodiment of a retention component used to retain multiple cutting elements.
  • the top portion of a blade 202 on a pre-formed bit 200 may be cut off, such as by wire EDM or other cutting methods, to separate the top and bottom sections of a blade and form retention component 206 .
  • the retention component 206 may be secured to the bit body 201 by brazing, welding, or mechanical locking, such as using threaded fasteners. While the outer surface of retention component follows the geometry of blade 202 , the under surface of retention component is shaped to interface with and retain cutting elements 204 a .
  • a drill bit 300 may include at least one blade 302 having a plurality of cutting elements 304 thereon.
  • Cutting elements 304 may include cutting elements 304 a retained on blade 302 by retention component 306 and cutting elements (not shown) retained on blade 302 by conventional brazing the cutting element (not shown) in a cutter pocket 308 .
  • retention component 306 interfaces a portion of the side surfaces of two cutting elements 304 a .
  • FIG. 3A and 3B interfaces a portion of the side surfaces of two cutting elements 304 a .
  • one or more of such cutting elements may be replaced by cutting elements retained on a blade by other means, including rotatable cutting element or mechanically retained cutting elements, where such retention mechanism only retains a single cutting element.
  • thermally stable diamond may be formed in various manners.
  • a typical polycrystalline diamond layer includes individual diamond “crystals” that are interconnected. The individual diamond crystals thus form a lattice structure.
  • a metal catalyst such as cobalt, may be used to promote recrystallization of the diamond particles and formation of the lattice structure.
  • cobalt particles are generally found within the interstitial spaces in the diamond lattice structure.
  • Cobalt has a substantially different coefficient of thermal expansion as compared to diamond. Therefore, upon heating of a diamond table, the cobalt and the diamond lattice will expand at different rates, causing cracks to form in the lattice structure and resulting in deterioration of the diamond table.
  • a cutter may be positioned on a blade with a selected back rake to assist in removing drill cuttings and increasing rate of penetration.
  • a cutter disposed on a drill bit with side rake may be forced forward in a radial and tangential direction when the bit rotates.
  • the radial direction may assist the movement of inner rotatable cutting element relative to outer support element, such rotation may allow greater drill cuttings removal and provide an improved rate of penetration.
  • any back rake and side rake combination may be used with the cutting elements of the present disclosure to enhance rotatability and/or improve drilling efficiency.
