Definitions

  • the invention relates to a drilling method for drilling semi-hard, hard or abrasive rocks using rotary drilling machines comprising a drilling rod with a cutting edge formed by a cutting body provided with inserts.
  • the invention also relates to a new rotary drilling machine.
  • Rotary drills can be used for rocks whose hardness is less than 800 bars and whose abrasiveness is zero, such as limestone and marl.
  • these devices are not efficient enough and we are led to use hammers or hammer drills.
  • hammers or hammer drills which associate a strike with drilling, are indeed more powerful but they are much more complex therefore of a higher cost and their noisier operation causes a noticeably greater annoyance for the users.
  • This fluid is generally water, used under a pressure of the order of 0-40 bars or air, used under a pressure close to 5 bars.
  • the invention relates to a drilling method for drilling semi-hard, hard or abrasive rocks using rotary drills comprising a drilling rod with a cutting edge constituted by a cutting edge body provided with plates, characterized in that the he cutting action of the inserts is combined at a given point in the drilling hole with that of fluid jets under very high pressure from 1000 to 4000 bars directed parallel to the drilling axis.
  • the invention also relates to a new rotary drilling machine comprising a drilling rod with a cutter constituted by a cutter body provided with inserts characterized in that the cutter provided with inserts is drilled with at least one micrometric hole of 1 to 50 microns for injecting the fluid under very high pressure from 1000 to 4000 bar.
  • the body of the cutter also has a larger lateral orifice (1 to 8 mm for example) allowing the injection of a fluid under low pressure.
  • This fluid can be air or water. In the case of water it is generally used under a pressure of 0-40 bars, in the case of air under a pressure close to 5 bars.
  • This additional injection is mainly intended for the transport, inside the hole of drilling of the rock particles which come from the cut operated by the combined action of the plates of the cutter and the jets of fluid under very high pressure.
  • the flow rate of the fluid at very high pressure from 5 to 251 / min, is indeed insufficient to ensure the rapid evacuation of the cutting dust, an essential condition for carrying out rapid drilling of the borehole.
  • the invention also relates to a new drilling rod comprising means for supplying the fluid under low pressure and the fluid under very high pressure.
  • the drilling rod comprises two concentric tubes, the central tube serving to supply the cutter with liquid under very high pressure and the external tube supplying it with fluid under low pressure.
  • the drill rod is supplied by a double injection device.
  • the cutting edge 1 as shown in FIG. 1 is of the skirted model. Any other classic model can be used. It is equipped with at least one size 2 wafer, for example made of tungsten carbide or other material having a very high hardness.
  • the inserts When the inserts are 2, 3 or 4 in number, they are generally arranged symmetrically with respect to the axis of the cutter.
  • the most common devices such as that shown in FIG. 2, comprise three plates arranged at 120 degrees but it is also possible, for example, to have two plates at 180 ° from one another or four plates at 90 °.
  • Each of these plates is pierced with at least one micrometric hole 3 along the drilling edge, this (these) hole (s) being intended for the injection of water under high pressure.
  • Each of the inserts is also preceded by a larger orifice 4 (of the order of 1-8 mm) drilled in the body of the cutter and located at the lower chip release part, intended for the injection of a fluid. under low pressure.
  • the micrometric holes are drilled in the body of the cutter and in front of the insert in the direction of rotation, the position of the orifice for injecting the fluid under low pressure. being unchanged.
  • FIGs 4 and 5 show in more detail the supply of the cutting edge by the fluids.
  • the micrometric holes are shown at 23, as drilled in the thickness of the plates. These holes are supplied by line 22, which is itself connected to the central tube 30 of the drill rod.
  • the cutter is fixed for example by screwing on the external tube 31 but it is supported on the internal tube 30 by means of the joint 33.
  • a device 32 of the star type for example makes these two tubes integral with one of the 'other.
  • the drill rod shown in Figure 6 consists of two concentric tubes 30 and 31.
  • the central tube 30 of small diameter is intended for the transport of water under very high pressure.
  • the external tube 31 is intended for transporting the fluid under low pressure.
  • the dimensions of these tubes vary according to the dimensions of the hole to be drilled.
  • the external tube generally has an external diameter of 25-27 mm and the internal tube a diameter of the order of 7-8 mm.
  • the outer tube generally has an outer diameter of around 90 mm and the inner tube a diameter of around 20 mm.
  • the two tubes are made integral by means of a suitable fixing or clamping device, for example a star device 32 as shown in FIG. 7.
  • the two tubes are guided in the center by the shoes 34.
  • the ends of the external tube 31 are threaded so that the rod can adapt to the hub of the drill at its rear part (see FIG. 8) and receive the cutting edge at its front part.
  • the drilling machine shown in FIG. 8 is essentially composed of a rotating hub 40 equipped with a double injection device. This hub is rotated by pinions 41 and 42 driven by a hydraulic motor 43. Water under high pressure is introduced into the hub 40 via a needle 45 of noble steel welded to the plate 46. This needle is supplied by a hose connected at 44 on the plate. The seal between the needle and the hub is achieved by a stack of felt seals 47 tightened by a cable gland 48. Holes 49 to evacuate any leaks are provided at the bottom of the plate and at the front of the hood.
  • the drilling rod constituted by the two concentric tubes 30 and 31.
  • the high pressure injection is thus in this way connected to the internal tube 30 which is itself maintained by the external tube 31 screwed into the hub, the seal being provided by the seal 33.
  • the front casing of the drilling machine is equipped with a floating ring 50 supported by seals 52.
  • the floating ring is guided on the hub and the seal is ensured by the seals 51.
  • the studs 54 ensure the fixing of the cover. 53.
  • the injection fluid circulates through the cover 53 then in the ring 51 and the hub 40 through the orifice 55.
  • the fluid injected under low pressure moves in the annular section between tubes 30 and 31.
  • the oil supply ports for the engine and the injection ports are the oil supply ports for the engine and the injection ports.
  • the engine oil is supplied through the orifice 60 while the return of this oil is carried out through the orifice 61.
  • An orifice 62 is provided for the drainage of any engine oil leaks.
  • the injection of low pressure fluid is carried out through the orifice 63 while the orifice 44 is used for the introduction of water under very high pressure.
  • the platelets and the film of high pressure water coming from micrometric hole (s) are used for cutting.
  • low pressure water is used as the secondary injection fluid, it is used both for the removal of dust and for its removal from the hole.
