The specific embodiment
With reference to Fig. 1, drill bit assembly 11 has the body 13 in its lower end.Body 13 has the end face 15 in its lower end.A plurality of blades 17 are formed on the end face 15 and from end face 15 and give prominence to, and have six blades 17 as shown in drawings.Blade 17 is from zone, guarantor footpath that the core of end face 15 outwards is directed in body 13 peripheries.Blade 17 is separated from one another, is formed for the chip area 19 by drilling fluid and drilling cuttings between them.Each blade 17 comprises delegation's tradition cutting edge, is generally polycrystalline diamond (PCD) cutting edge.Nozzle 23 is discharged drilling fluids, and drilling fluid flows through chip area 19 together with drilling cuttings and from the well outflow that falls back.Although shown drill bit assembly 11 is " drag bit " or steel body drill bit, but the instruction at this is applicable to that also tricone bit or casting drill bit are (such as the RE that redistributes 37 shown in Figure 1, drill bit in No. 127 United States Patent (USP)s), this should be conspicuous for a person skilled in the art.
The main footpath liner (primary gage pad) 25 of protecting of one cover is integrally formed on the side of drill body 13.In an illustrated embodiment, each main protects footpath liner 25 in the blade 17 and from its longitudinal extension.Alternatively, the main footpath liner 25 of protecting can tilt or helical buckling with respect to axle.Each main footpath liner 25 of protecting is given prominence to from body 13, extends chip area 19.Main size of protecting footpath liner 25 makes its guarantor footpath or diameter place in the well that is cut have external surface 26.External surface 26 comprises wearing face, but this external surface is smooth and does not have any cutting structure.Drill body 13 can use casting or machining process to be formed by metallic matrix synthetic or steel together with blade 17 and guarantor footpath liner 25.
With reference to Fig. 2, steel screw thread coupling or base 27 are connected to the upper end of body 13.Base 27 is incorporated on the body 13 in casting process.Base 27 is given prominence to from body 13 upper ends and is had screw thread 29 in its outside.Axial passage 31 extends through base 27 and connects nozzle 23 to be used to transmit drilling fluid.
Shank (shank) 33 is fixed on the base 27.Shank 33 is also formed by steel, rather than is formed by the carbide matrix.Shank 33 is cylindrical members, and this cylindrical member can have the length longer than the axial dimension of body 13.Shank 33 has the threaded block 35 that engages with the screw thread 29 of base 27.Inclined-plane or oblique angle 37 are formed on the lower end of shank 33.Similarly, oblique angle 39 is formed on the upper end of body 13.Relative oblique angle 37,39 forms V-ring shape cavity.This cavity is full of welding material 41, by this welding material shank 33 for good and all is connected on the drill body 13.Shank 33 has the axial passage 43 that is used to transmit drilling fluid that aligns with passage 31.Shank 33 has threaded 45 in the top.The size of pin 45 is suitable for being fixed to the drill string lower end.
Handle drill bit assembly 11 with the traditional approach that other drag bit assembly that can lead is used.This drill bit assembly generally is fixed on the turbine or MTR of drill string lower end.Drilling fluid along the drill string pumping drives MTR, thereby causes drill bit 11 rotations.Separated guarantor footpath liner 25 is stablized drill bit 11 so that well bore wall meets the requirements of situation, prevents to produce convex shoulder and other irregular conditions (irregularities).
Hardfacing materials on external surface, leading edge and the trailing edge typically comprises the soldered tungsten carbide material that puts in place.Technology according to the welder; weld this hardfacing materials and may produce the flaw and the region of high stress, make to cause hardfacing materials to be intended to utilize the surface of its abrasion resistance protection to downcut or disengaging from it along the welding bead line or at the hardfacing materials lodgment.Owing to be applied in the geometry on the surface of hardfacing materials, even skilled welder, the process of face of weld hardened material also may be time-consuming, difficulty and tediously long.Some surfaces such as the inner surface that is engaged with each other, can not utilize the hardfacing materials of welding exactly.
The hard facing metal matrix has been used on the inner surface of bearing.The hard facing metal matrix typically is the form of easily curved thin plate.The shape that needs on case hardening surface is cut down from easily curved thin plate, is welded to then on target surface or the surface to be hard-faced.Previous easily curved case hardening thin plate comprises metallic matrix, and this metallic matrix typically comprises the crystallite tungsten carbide mostly or has the still less macrocrystalline tungsten carbide of nickel chromium triangle.
With reference to Fig. 3, shown the case hardening base sheet 101 that is in easily curved state.Case hardening base sheet 101 comprises hardfacing materials matrix 103 and along the adhesive surface 105 on a surface.Adhesive surface 105 helps to keep before welding case hardening base sheet 101 against target surface.
With reference to Fig. 7, spherical cast tungsten carbide 117 can comprise many shapes.Preferably, the spherical cast tungsten carbide of in matrix 103, using 117 basically shape as spheroid or spherical 117a.Yet spherical cast tungsten carbide 117 also can be as the spheroid form or the oblong 117b that stretch of soffit from it.Alternately, spherical cast tungsten carbide 117 can be as the spheroid form or the flat pattern 117c of soffit compression from it.The shape of the sphere of spherical cast tungsten carbide 117, prolate shape and pancake 117a, 117b, 117c is because the manufacture method of spherical cast tungsten carbide 117 causes, and the title that is used for the spherical cast tungsten carbide that example explanation mentioned should matrix 103 not to be confined to only be spherical 117a, but also comprise the cast tungsten carbide matrix of prolate shape and pancake 117b, 117c.
With reference to Fig. 4, case hardening base sheet 101 is cut the shape of wanting with formation along template 107.As shown in Figure 5, template 107 is preferred corresponding to the surface on the drill bit assembly 11.Template 107 shown in Figure 4 is corresponding to external surface 57.Yet, as shown in Figure 5, can be from different template 107a, the 107b of case hardening base sheet 101 cutting with corresponding to the surface that needs on the drill bit assembly.For example, template 107a is corresponding to external surface 26, and template 107b is corresponding to the body between the blade 17 13.In addition, case hardening base sheet 101 also can be cut into the template corresponding to drill bit assembly 11 inner surfaces.
With reference to Fig. 6, the hardfacing materials matrix 103 on template 107a, 107b after the welding and the microgram that needs the interface between the external surface of drill bit assembly 11 have been shown.Coat district 109 and comprise hardfacing materials matrix 103, hardfacing materials is all wrapping up everywhere basically equably densely.As mentioned above, special hardfacing materials can in the nickel chromium triangle matrix, comprise independent, combination with one another or with spherical sintered tungsten carbide, spherical cast tungsten carbide or the glassy metal of crystallite or macrocrystalline tungsten carbide combination.Because fusion process, land 111 is the pure metallurgical binding districts between the external surface of needing at hardfacing materials matrix 103 and drill bit assembly 11.Land 111 have high interparticle bond strength and help to reduce cracked, peel off and crackle.Diffusion zone 113 is caused by fusion process.Land 111 comprises from the nickel chromium triangle of template 107a, 107b with from the iron of substrate or drill bit assembly 11.Typically, substrate or drill bit assembly 11 keep its most of mechanical performance equably.But thermal treatment zone 115 comprises the remainder of drill bit assembly 11 substrates.If desired, zone 115 can be by heat treatment so that recover may be by any mechanical performance of the drill bit assembly 11 of deterioration in fusion process.
Though only shown the present invention, yet it will be apparent to those skilled in the art that and the invention is not restricted to this, but allowed and carry out various changes and can not depart from scope of the present invention with its some forms.For example, drill bit assembly also can be tricone bit or casting drill bit.
