Definitions
- the greatest radius swept by a reamer may be the radial distance from the axis to the extremity of the outermost cutter (s).
- a supporting structure In order to position a reamer centrally in the reamed borehole, it is customary for a supporting structure to include a section which does not include cutters but has a so-called gauge pad (alternatively spelt "gage pad") which is a surface positioned to confront and slide on the wall of the reamed borehole.
- gauge pad alternatively spelt "gage pad"
- the particulate material may consist of 30 to 100% of hard material possibly from 50% to 100% of hard material while the balance (if any) of particulate material with Knoop hardness less than 1000 may be steel, alloy steel or other metal.
- a second aspect of the present disclosure can be stated as a rotary cutting tool for incorporation into a drill string to enlarge an underground conduit, comprising a tool body having a longitudinal axis extending between upper and lower ends with connectors at the upper and lower ends for attaching to the drill string and further comprising a plurality of cutter assemblies attached to the tool body at positions distributed azimuthally around the longitudinal axis of the tool, wherein each cutter assembly comprises a supporting structure bearing a plurality of cutters with exposed hard cutting surfaces providing the cutters' leading surfaces in the direction of rotation of the tool, and wherein the supporting structure is a body of particulate material infiltrated with a metal binder, the composition of the particulate material varying progressively from a first region of the support structure which is bounded by a surface positioned to contact the conduit wall to a second region which is spaced from the first said region (and which may be attached to the tool body) such that the first region contains particulate material with Knoop hardness of at least 1000
- a fourth possibility is that these objects are pieces of material, providing smooth lubricious areas in a radially outward surface of the body of particulate material. This may reduce drag from sliding contact with a surface already traversed by one or more of the cutters.
- Material to provide lubricious areas may be bronze, copper or a high carbon steel.
- Further aspects of the present disclosure are methods of making a rotary cutting tool by an additive manufacturing process comprising forming the body of particulate material which is the support structure as a succession of layers of particulate material, wherein at least some layers include particulate material having a Knoop hardness of at least 1000 and then infiltrating the particulate material with a molten metallic binder. The particulate material in the layers may change progressively in composition as some of the layers are deposited.
- Fig 1 shows an exemplary drilling assembly which includes an
- a drill string 12 extends from a drilling rig 10 into a borehole. An upper part of the borehole has already been lined with casing and cemented as indicated at 14.
- the drill string 12 is connected to a bottomhole assembly 18 which includes a drill bit 20 and also includes an under-reamer 22 included in the drill string 12 at a position somewhat above the drill bit 20.
- the under reamer 22 is connected to the drill string 12 at standard connectors 40, 42 (indicated schematically) at upper and lower ends of the reamer. [0043]
- the under reamer 22 has been expanded beneath the cased section 14. As the drill string 12 and bottomhole assembly 14 are rotated, the drill bit 20 extends a pilot hole 24 downwards while the reamer 22 simultaneously opens the pilot hole 24 to a larger diameter borehole 26.
- Each recess 116 accommodates a cutter assembly 44 in its retracted position.
- the three cutter assemblies are similar in construction and dimensions.
- the radially outer face 45 of the cutter assembly 44 is indicated without detail in Figs 2 and 3.
- One cutter assembly is shown in larger side and face views in Figs 4 and 5.
- the side face shown by Fig 4 is the leading face in the direction of rotation of the tool.
- Each cutter assembly 44 comprises an inner block 46 and an outer block 48 which is a support structure for a number of cutters.
- the outer block 48 is bolted to the inner block 46 by bolts, not shown.
- Both side faces of the inner block 46 have protruding ribs 117 which extend at an angle to the tool axis. Ends 124 of ribs 117 are seen in Fig 5.
- the piston 130 sealingly engages the inner mandrel 150 at 152, and sealingly engages the body 106 at 134.
- a lower cap 180 provides a stop for the downward axial movement of piston 130. This cap 180 is threadedly connected to the body 106 and to the lower retainer 170 at 182, 184, respectively. There is sealing engagement between the lower cap 180 and the body 106.
- the cutters 53 and 211-216 are poly crystalline diamond cutters
- Such cutters have a disc 57 of sintered diamond crystals formed at one end of a cylindrical body 59 which may be sintered tungsten carbide particles.
- the body 59 of each cutter fits into a cavity, often referred to as a pocket, formed in the cutter support structure which is the outer block 48 so that the cutter is partially embedded in the outer block 48 and its disc 57 of diamond particles is exposed as a hard cutting surface.
- Securing the body 59 of a cutter in a pocket in the outer block 48 may be done by brazing although it is also possible for a cutter to be secured mechanically in a way which allows it to rotate around its own axis thereby distributing wear.
- the cutters 211-214 are partially embedded in the outer block 48 in a similar manner to the cutters 215, 216.
- the outer face of the block includes part-cylindrical surfaces 231-234 which extend behind the leading faces of cutters 211-214 respectively and which are aligned radially with the extremities of the respective cutters.
- Each of the part-cylindrical surfaces 231- 234 has a radius which lies on the tool axis when the cutter assemblies 48 are fully expanded.
- These surfaces 231-234 act as secondary gauge areas: the surface 231 slides over rock which has just been cut by the action of cutter 211, surface 232 slides over rock cut by cutter 232 and so on. These secondary gauge areas 231-234 contributes to stabilisation of the position of the rotating tool as it advances axially, even though the rock surfaces created by cutters 211-214 have only a transient existence, because they are cut away by cutters at a greater radius as the tool advances.
- the outer block 48 includes cavities for cutters and through holes for bolts which attach the outer block to the inner block 46. These internal spaces can be created by inserting sacrificial objects into the mould at the required positions and packing the particulate material around them.
- Figs 11 to 13 show a variation on the procedure of Figs 8 to 10.
- the same mould 260 is used, but the mould is initially held at an angle as shown in Fig 11 while the particular material for the layer 252 is placed in it.
- this layer 252 lies in contact with the side face 261 of the mould as well as face 262.
- the binder may be drawn into the mass of particulate material by
- the binder which is used for infiltration should have a melting point below the melting points of the particulate materials, so that the particulate materials remain solid while the molten binder fills the space between particles.
- the binder may be chosen to have a melting temperature of not greater than 1300°C and possibly not greater than 1250, 1200 or even 1150°C so as to have a melting temperature below the melting temperature range of iron and steel.
- the binder may be chosen to have a melting temperature of at least 800°C and possibly at least 900 or 950°C.
- a related, but slightly different approach is to provide the required tungsten carbide and steel particles in the form of particles coated with a meltable organic coating. After each layer has been deposited, the required areas can be selectively heated to bind particles together and to the layer beneath in accordance with a digital design.
- a process of this type, using selective heating with a laser beam to fuse resin coated metal particles is disclosed in US 5433280 for the purpose of making drill bits.
- the layers which are deposited may be progressively varied in composition, starting with tungsten carbide, then continuing using mixtures of tungsten carbide and steel and finishing with steel (or the other way around). Since the process uses a large number of thin layers it would be possible to have a very smooth transition from tungsten carbide to steel particles.
- a different approach to additive manufacturing is to deposit a plurality of particulate materials selectively to make both the block and a surrounding mould as a succession of layers. Apparatus for depositing the materials uses two or more devices which are controllable to deliver small quantities of powder and which are movable over a work area to deposit in accordance with a digital design.
- Fig 15 shows that when the refractory enclosure 270 has been filled, the top plate 274 of the table comes to rest on an inwardly projecting lip 284, allowing the enclosure 270 and its contents to be moved to a vacuum furnace where infiltration with molten metallic binder is carried out.
- the drill string is then rotated and the tool is expanded by pumping fluid into flowbore 108 as described above.
- the radially outer edge of cutter 313 contacts the interior face of the tubing 72 and cuts into it. This allows expansion to continue and the cutters 312 and 311 contact the inside face of the tubing 72 in sequence, cutting into and through the tubing until the fully expanded position of the inner and outer blocks 46, 348 is reached.
- the tool is then advanced axially in the direction indicted by arrow D.
- the leading cutter 311 on each cutter block is positioned to cut away any corrosion or deposits and also remove some material from the inside wall of the tubing 72, thus exposing a new inward facing surface 354.
- the cutter 312 which extends outwardly beyond the cutter 311 removes a further thickness from the tubing 72, thus exposing a new inward facing surface 356.
- the remainder of the tubing indicated outside this new surface 356 is then removed by cutter 313 so that the full thickness of the tubing 72 has been removed.
- the cutter 313 also cuts into the cement 74 which was around the outside of the tubing. Radially outward facing surfaces of the outer block 348 thus make sliding contact with surfaces 354 and 356 transiently formed on the tubing 72 and with the cement 74.
- the outer block 348 is made of particulate material in layers which are infiltrated with metallic binder which to unites the layers of particulate material into a single article.
- metallic binder which to unites the layers of particulate material into a single article.
- tungsten carbide is used for the radially outward layer 252 so that the surfaces which slide on the tubing 72 and the cement are hard and wear resistant.
- the particulate material in the inward layer 254 is steel and the intermediate layers 256-259 contain mixtures which give a progressive change in composition.
