Definitions

  • the disclosed approaches are somewhat generalized in nature and fail to accommodate or implement an engineered approach to achieving a target ROP in combination with more stable, predictable bit performance. Furthermore, the disclosed approaches do not provide a bit or method of drilling which is generally tolerant to being axially loaded with an amount of weight-on-bit over and in excess what would be optimum for the current rate-of-penetration for the particular formation being drilled and which would not generate high amounts of potentially bit-stopping (e.g., stick-slip) or bit-damaging torque-on-bit should the bit nonetheless be subjected to such excessive amounts of weight-on-bit.
  • bit-stopping e.g., stick-slip
  • FIG. 2 shows a partial view of the drill bit having the attached bearing block of FIG. 1 .
  • first and second thicknesses 56 and 58 may be different, as illustrated, enabling the bearing block 50 to be designed specifically for a particular application in order to achieve optimal TDOC for different cutters 14 associated with the block 50 .
  • the TDOC may be modified for different applications for a given bit frame or bit body by providing a block having the desired thickness or thicknesses without necessitating modification to the bit frame or bit body.
  • the bearing block 50 of this embodiment is “peanut-shaped,” as is the complementary socket 60 of a blade 62 ( FIG. 5A ), that the shape of the bearing block 50 and socket 60 may take on any shape consistent with the capabilities of manufacturing of such structures.
  • a keyed bearing block 70 includes three different thicknesses 76 , 77 , and 78 and three different rubbing surfaces 72 , 73 , and 74 , respectively.
  • the bearing block 70 is “keyed” in the sense of providing two or more thicknesses, each thickness may be associated with one or more adjacent cutters when bearing block 70 is attached to a bit body or frame.
  • the bearing block 70 is “keyed” in that each rubbing surface may exhibit an inclination (tilt) or a complex contour and be specifically tied to the TDOC to be provided a given cutter or cutters, in order to provide a combination of TDOCs within a single bearing block.
  • the angle of inclination may be selected to approximate a helix angle traveled by a cutter as it rotates and travels with the bit at a specific radial location on the bit face when the bit operates at a selected rate of penetration (ROP) or range of ROPs.
  • the bearing block 70 comprises thicknesses 76 , 77 , 78 having rubbing surface 72 tilted toward its leading side, the rubbing surface 73 that is substantially flat, and the rubbing surface 74 being substantially round or convex, respectively.
  • the cutters (not shown) of a blade 82 will provide highly precise TDOCs, which may also advantageously enable the bearing block 70 to have one or more advantageous contact levels and orientations with the formation being drilled.
  • the bearing block 70 may be secured to the receptacle 80 of the blade 82 by a brazing process 86 .
  • a concave bearing block 130 is shown.
  • the concave bearing block 130 may be bonded by a braze alloy 138 to a receptacle 132 in a blade 140 .
  • the concave bearing block 130 may include a base portion 134 partially received within the receptacle 132 and a distal portion 135 including a rubbing surface 136 .
  • the bearing block 130 may include a first material forming the distal portion 135 (e.g., the rubbing surface 136 ) and a second material forming the base portion 134 .
  • the distal portion 135 may be formed from a relatively softer material selected for wear and the base portion 134 may be foamed from a relatively harder material selected for resistance to wear.
  • a drill bit having the bearing block 130 disposed in the blade 140 of the drill bit may be designed to initially contact a subterranean formation during a drilling process with the distal portion 135 formed from the relatively softer material.
  • the relatively softer material will wear during the operation causing the DOC to increase and exposing the relatively harder material of the base portion 134 disposed proximate to the receptacle 132 in the blade 140 of the drill bit.
  • a bearing block 190 including a rounded (i.e., a convex shape), enlarged distal portion 195 having a rubbing surface 196 is shown.
  • the distal portion 175 is enlarged relative to a base portion 194 of the bearing block 190 .
  • the bearing block 190 may provide an enlarged rubbing surface 196 at the distal end of the bearing block 190 .
  • the enlarged rubbing surface 196 may provide a greater surface area of the rubbing surface 196 or rubbing surfaces of multiple bearing blocks enabling for improved flexibility in the WOB applied to the drill string.
  • the bearing block may comprise a “harder” material exhibiting high hardness and wear-resistant properties such as abrasion- and erosion-resistant characteristics.
  • So-called “harder” materials may comprise materials such as tungsten carbide, natural or synthetic diamond (polycrystalline diamond compact (PDC) or thermally stable polycrystalline (TSP)), ceramic materials, or impregnated materials composed of diamond material, such as natural or synthetic diamond grit, dispersed within a matrix of wear resistant material.
  • PDC polycrystalline diamond compact
  • TSP thermally stable polycrystalline
  • Use of harder materials in the bearing block may allow for a relatively consistent DOC during a drilling operation through one or more formations. That is, the harder, wear-resistant bearing block will substantially maintain its thickness throughout the drilling operation. Thus, an initially TDOC specified will be substantially maintained during a drilling operation.
  • Such a bearing block may exhibit a reduced coefficient of friction between the rubbing surface of the bearing block and the formation as the rubbing surface travels across the formation as compared to another rubbing surface of the drill bit (i.e., another surface of the drill bit that contacts the formation during a drilling process).
  • a rubbing surface of a portion of the bit body of the drill bit e.g., the blades 18 of the drill bit 10
  • a bearing block exhibiting a reduced coefficient of friction as compared to another rubbing surface of the drill bit may allow for reduced torque in the drill string as the rubbing surface of the bearing block travels across the formation.
  • increasing the WOB increases the forces between the bearing block and the cutting elements increase and also increases the amount of torque required to turn the drill string. Therefore, providing a bearing block with a rubbing surface exhibiting a lower coefficient between the rubbing surface and the formation will allow for reduced torque in a drill operation under a given amount of WOB. Further, reduced friction reduces the amount of torque required to rotate the drill bit, which may be significant in directional drilling using downhole motors wherein the torque output is limited.
  • the DOC will increase until the thickness 78 of the harder rubbing surface 72 is equal to or greater than that of the thickness 76 of the softer rubbing surface 74 .
  • the rubbing surface 136 of the bearing block 130 may comprise a softer material, as described above.
  • the base portion 134 may comprise a harder material, as also discussed above.
  • the rubbing surface 136 of the bearing block 130 may provide an initial DOC. However, as the rubbing surface 136 is reduced, the DOC will increase until the base portion 134 is exposed.
  • the bearing block may be located substantially in the cone region on a blade of the bit frame, in the cone/nose region, in the nose region, etc.
  • the interchangeable, modifiable bearing block according to embodiments of the invention brings manufacturing selectability by providing a customizable product suitable for use with a common bit frame, thus, not requiring a complex assortment of stocked bit frames.
  • Each bearing block is selectably insertable into a bit frame, enabling a bit to be customized or adapted for different drilling applications, including difficult formations, or for different drilling systems.
  • different cutting characteristics may be advantageously obtained without affecting or requiring alteration of the bit frame.
  • the bearing block may be designed for specific associated cutters or sets of cutters to obtain customized cutter profiles and TDOCs, due to the ability of the bearing block with a customized profile and wear properties to be connected to a common bit frame without alteration thereto.
