Definitions
- This invention relates in general to drill bits for well drilling, and in particular to a metallic hardfacing matrix and method of applying the metallic hardfacing matrix to drill bits.
- Rotary well drilling for oil and gas is primarily accomplished through one of two types of bits, hi a rotary cutter bit, the bit body has typically three rotatable cones or cutters. The cones rotate on bearing pins and have teeth or tungsten carbide inserts for disintegrating the earth formation.
- the bit body In the fixed cutter or drag bit type, the bit body has a face which contains cutting elements mounted on fixed blades. The cutting elements are typically polycrystalline diamond.
- the bit body has drilling fluid passages with nozzles for discharging drilling fluid through junk slots that are located between the blades.
- Drag bits are extensively used in directionally drilling, particularly in the technique referred to as steerable drilling.
- the drill bit is steered in desired directions for cutting borehole segments as it progresses.
- a mud motor or turbine is employed with the bit assembly for rotating the drag bit while the drill string remains stationary.
- Hardfacing or wear-resistant materials are typically connected to the outer surfaces of drill bits to help reduce wear and maintain the efficiency of the drill bit.
- Commonly used hardfacing includes tungsten carbide particles that are welded in place on the outer surface of the drill bit.
- U.S. Reissue Patent Number RE 37,127 provides an in depth discussion of hardfacings, and is incorporated herein by reference in its entirety. Even with skilled welders, imperfections can be present due to varying thicknesses of the weld, shape of the drill bit the hardfacing is being welded upon, and the beads associated with welding processes. Machining can be time-consuming and expensive. Moreover, hardfacing was not welded to inner parts due to narrow clearances and expense. DISCLOSURE OF THE INVENTION
- a method of increasing the durability of a drill bit which includes the step providing a pliable sheet of a hardfacing matrix material.
- the pliable sheet of hardfacing material has a nickel and chromium matrix combined with a first element.
- the first element is selected from a group consisting of spherical sintered tungsten carbide, spherical cast tungsten carbide, and metallic glass.
- the hardfacing matrix material sheet is placed on a preselected surface of the drill bit. The hardfacing matrix material sheet is then fusion bonded to the drill bit.

- Figure 7 are schematic perspective views of various forms of spherical cast tungsten carbide in accordance with this invention.
- bit assembly 11 has a body 13 on a lower end.
- Body 13 has a face 15 on its lower end.
- a plurality of blades 17 are formed on and protrude from face 15, with six blades 17 being shown in the drawings.
- Blades 17 lead outward from a central portion of face 15 to a gage area at the periphery of body 13.
- Blades 17 are separated from each other, defining junk slots 19 between them for the passage of drilling fluid and cuttings.
- Each blade 17 contains a row of conventional cutters typically polycrystalline diamond (PCD).
- Nozzles 23 discharge drilling fluid, which flows through junk slots 19 and back up the borehole along with the cuttings.
- bit assembly 11 is illustrated as a "drag bit” or steel-bodied bit, it should be readily apparent to those skilled in the art that the teachings herein are also applicable to tri- cone bits, or cast bits, such as those illustrated in Figure 1 of U.S. Reissue Patent
- a set of primary gage pads 25 is integrally formed on the sides of bit body 13.
- Each primary gage pad 25 is contiguous with and, in the embodiment shown, extends longitudinally from one of the blades 17. Alternately, primary gage pads 25 could be inclined relative to the axis or curved in a spiral. Each primary gage pad 25 protrudes from body 13, extending the junk slots 19. Primary gage pads 25 are dimensioned to have an outer surface 26 at the gage or diameter of the borehole being cut. Outer surface 26 contains wear resistant surfaces, but is smooth and free of any cutting structure. Bit body 13, along with blades 17 and gage pads 25, may be formed of a metal matrix composite or steel using a casting or machining process.
- a steel threaded coupling or blank 27 is joined to an upper end of body 13.
- Blank 27 is bonded to body 13 during the casting process.
- Blank 27 protrudes from the upper end of body 13 and has threads 29 on its exterior.
- An axial passage 31 extends through blank 27 and joins nozzles 23 for delivering drilling fluid.
- a shank 33 is secured to blank 27.
- Shank 33 is also formed of steel, rather than of a carbide matrix.
- Shank 33 is a cylindrical member that may have a length longer than the axial dimension of body 13.
- Shank 33 has a threaded receptacle 35 which engages threads 29 of blank 27.
- a chamfer or bevel 37 is formed on the lower end of shank 33.
- a bevel 39 is formed on the upper end of body 13.
- the opposed bevels 37, 39 create a V-shaped annular cavity. This cavity is filled with a weld material 41, the welding permanently joining shank 33 to bit body 13.
- Shank 33 has an axial passage 43 which registers with passage 31 for delivering drilling fluid.
- Shank 33 has a threaded pin 45 on its upper end. Pin 45 is dimensioned for securing to a lower end of a drill string.
- Bit assembly 11 operates in a manner that is conventional with other steerable drag bit assemblies. It is normally secured to a turbine or mud motor which is at the lower end of drill string. Drilling fluid pumped down the drill string drives the mud motor, which in turn causes rotation of bit 11.
- the spaced apart gage pads 25 stabilize bit 11 to condition the borehole wall, preventing ledging and other irregularities.
- the hardfacing on outer surfaces and leading and trailing edges typically comprises a tungsten carbide material that is welded into place. Depending on the skill of the welder, welding such hardfacing can create imperfections and high stress zones along the weld bead lines or in the hardfacing deposit that can lead to the hardfacing chipping off or disengaging from the surface it is meant to protect with its wear- resistant properties. Even for skilled welders, the process of welding hardfacing can be time consuming, difficult, and tedious due to the geometry of the surfaces to which the hardfacing material is being applied. Some surfaces, like internal surfaces that engage each other, are simply not available for welded hardfacing.
- a hardfacing metal matrix has been used on the internal surfaces of bearings.
- the hardfacing metal matrix typically comes in the form of a pliable sheet.
- a desired shape of the hardfacing surface is cut out of the pliable sheet and then fusion bonded onto the target surface, or the surface to be hardfaced.
- Previous pliable hardfacing sheets comprised a metal matrix that typically included mostly either microcrystalline tungsten carbide or macrocrystalline tungsten carbide with lesser amounts of nickel and chromium.
- Hardfacing matrix sheet 101 is shown in its pliable state.
- Hardfacing matrix sheet 101 comprises a hardfacing material matrix 103 and an adhesive surface 105 along one surface.
- Adhesive surface 105 helps to hold hardfacing matrix sheet 101 against the target surface prior to fusion bonding.
- Hardfacing material matrix 103 preferably comprises spherical sintered tungsten carbide, spherical cast tungsten carbide, or a nanosteel composite also known as "metallic glass.”
- U.S. Patents 6,689,234 and 6,767,419 provide a discussion of metallic glass and disclose various methods of applying metallic glass to a substrate.
- U.S. Patents 6,689,234 and 6,767,419 are incorporated herein by reference in their entireties.
- Matrix 103 can also comprise a combination of at least two of spherical sintered tungsten carbide, spherical cast tungsten carbide, and metallic glass.
- Microcrystalline and macrocrystalline tungsten carbide can also be added to matrix 103 having spherical sintered tungsten carbide, spherical cast tungsten carbide, or metallic glass, alone or in combination.
- Crushed cast tungsten carbide and crushed sintered tungsten carbide may also be added to matrix 103 having spherical sintered tungsten carbide, spherical cast tungsten carbide, or metallic glass, alone or in combination.
- spherical cast tungsten carbide 117 can comprise numerous shapes.
- spherical cast tungsten carbide 117 for use in matrix 103 will be substantially shaped like a sphere or spherical-shaped 117a.
- spherical cast tungsten carbide 117 but it can also be shaped like a sphere that has been stretched from its upper and lower surfaces, or prolate-shaped 117b.
- spherical cast tungsten carbide 117 can be shaped like a sphere that has been compressed from its upper and lower surfaces, or oblate-shaped 117c.
- Spherical-, prolate-, and oblate- shaped 117a,l 17b, 117c shapes of spherical cast tungsten carbide 117 are due to the manufacturing methods of spherical cast tungsten carbide 117 and are useful to illustrate that the name spherical cast tungsten carbide should not limit matrix 103 to only spherical-shaped 117a rather than including prolate- and oblate-shaped 117b, 117c matrixes of cast tungsten carbide.
- hardfacing matrix sheet 101 is cut along pattern 107 to form a desired shape.
- pattern 107 preferably corresponds to a surface on bit assembly 11.
- Pattern 107 shown in Figure 4 corresponds to outer surface 57.
- various patterns 107a, 107b can be cut from hardfacing matrix sheet 101 to correspond with desired surfaces on bit assembly.
- pattern 107a corresponds with outer surface 26, and pattern 107b corresponds with body 13 between blades 17.
- hardfacing matrix sheet 101 can also be cut with patterns to correspond to interior surfaces of bit assembly 11.
- Patterns 107a, 107b are placed on the desired surfaces of bit assembly 11.
- Figure 5 illustrates bit assembly 11 with patterns 107a, 107b being placed onto various desired surfaces.
- Adhesive 105 initially secures patterns 107a, 107b to the desired surfaces of bit assembly 11.
- Bit assembly 11 with the secured patterns 107a, 107b attached thereto is placed into a furnace.
- bit assembly 11 with patterns 107a, 107b is placed in the furnace for about five to ten minutes at about 2100 degrees Fahrenheit to fusion bond the hardfacing matrix on patterns 107a, 107b onto the desired outer surfaces of bit assembly 11.
- hardfacing material matrix 103 can be machined from a rough surface to a smoother surface as desired.
- Cladding region 109 comprises hardfacing material matrix 103 with the hardfacing material being densely packed substantially uniformly throughout.
- the particular hardfacing material can be in a nickel and chromium matrix including spherical sintered tungsten carbide, spherical cast tungsten carbide, or metallic glass individually, in combination with each other, or in combination with microcrystalline or macrocrystalline tungsten carbide.
- Bond region 111 is a true metallurgical bond region located between hardfacing material matrix 103 and the desired outer surfaces of bit assembly 11 due to the fusion bonding process.
- Bond region 111 has high interparticle bond strength and helps to reduce chipping, flaking and cracking. Diffusion zone region 113 results from the fusion bonding process. Bond region 111 comprises nickel and chromium from patterns 107a, 107b and iron from the substrate or bit assembly 11. Typically, the substrate or bit assembly 11 uniformly retains most of its mechanical properties. Heat treatable region 115 includes the remainder of the substrate of bit assembly 11. Region 115 can be heat treated, if necessary, to restore any mechanical properties of bit assembly 11 that may have deteriorated to the fusion bonding process.
- bit assembly can also be a tri-cone bit, or cast bit.
