Definitions

  • the present invention relates to a device for ensuring the verticality during drilling of a perforating machine and more particularly for controlling the verticality of such a machine comprising a suspended chassis on which is mounted a drilling head.
  • Machines of this type suspended for example from a cable, a hose or rods, are used in particular on oil sites and for the execution of foundations in all types of hard or soft ground.
  • the chassis serving as a guide and / or simple gravity ensures the verticality of the machine.
  • this chassis is fully sunk below the earth's surface, and the variations in hardness of the ground tend to deflect it, there is no direct mechanical means available to control the verticality of the machine and therefore the drilling.
  • the present invention aims to overcome this drawback by providing a device making it possible to control the verticality of a perforating device at any time, including when this device is entirely below the surface of the ground.
  • the invention provides a device for ensuring the verticality of a perforating machine comprising a suspended chassis on which is mounted a drilling head, characterized in that said drilling head is fixed on a connected connecting member orientably to a support member secured to the chassis.
  • the verticality of the drilling can thus be ensured by suitably orienting the drilling head with respect to the chassis, by virtue of a relative displacement of the connecting member with respect to the support member.
  • the connecting member and the support member are two metal plates normally in contact with each other, means being provided for moving the plate in a chosen direction support plate connection.
  • These plates can for example be substantially horizontal.
  • the connecting plate is mounted on the support plate by means of at least two elastic members each opposed to a jack with respect to the direction of orientation.
  • the elastic member located on the same side as this jack deforms in a first direction to allow the spacing of the plates, while the other elastic member deforms in a second direction forming a hinge.
  • the elastic members may include a stud with clearance through one of the plates and screwed into the other plate with the interposition of compressible elements.
  • the stud can pass through either the connecting plate or the support plate with clearance by being screwed respectively into the support plate or into the connection plate, the compressible elements being able to be interposed, either between the head of the stud and the plate traversed game, either between the two plates.
  • the compressible elements may for example comprise a stack of Belleville washers.
  • the maximum possible compression of the compressible elements is limited by a sleeve engaged on the stud in parallel with these elements.
  • the body of the jack can be formed by a hole drilled in one of the plates, in which a piston is placed, said hole opening out into the face of this plate opposite the other plate.
  • This protection can also be provided by a skirt made of elastic material such as rubber, disposed around the two plates to prevent the penetration of the drilling mud during the spacing of the plates.
  • the device according to the invention can in particular be adapted to control the verticality of a drilling rig whose drilling head comprises a pair of tools rotating in opposite directions so that the verticality of the drilling rig is ensured in the tool rotation plane by adjusting the difference in tool rotation speed.
  • the connecting member can be pivotally mounted relative to the support member around at least one horizontal axis parallel to the plane of rotation of the tools.
  • the drilling head can be tilted on either side of the mean plane of rotation of the tools, in order to control the verticality of the drilling machine in the direction perpendicular to this plane.
  • the device can comprise two rows of elastic members arranged on either side of the median plane of the device parallel to the plane of rotation of the tools.
  • the pivoting of the drilling head then takes place as a function of its direction, around one or other of the axes materialized by the rows of elastic members.
  • the perforating machine shown in Figures 1 to 3 comprises in known manner a frame 1 suspended by a member 2 to a lifting machine and supporting a drilling head 3 which comprises two twin pairs of tools 4 and 4 ', each pair of tools being driven by a hydraulic motor supplied from the surface by pipes 5.
  • the two pairs of tools 4 and 4 ′ rotate in opposite directions, as indicated by the arrows in FIG. 1.
  • a support plate 6 supporting the drilling head 3 is fixed to the lower part of the chassis 1.
  • a connecting plate 7 is fixed under the plate 6 as follows:
  • Two rows of threads 8 are produced in the plate 7 on either side of the axis of symmetry X-X of the device. In correspondence with these threads, holes 9 are made in the plate 6 with a diameter greater than the nominal diameter of the threads 8.
  • the plate 7 can move away from the plate 6 at an angle as shown in FIG. 5 where the gold sees that the studs 10 and the holes 9 are offset.
  • FIG. 6 Another set of studs 15 engaged in threads 15 ′ (FIG. 6) ensures the attachment to the connecting plate 7 of the plate 26 itself secured to a frame 16 to which the drilling head is fixed.
  • the drilling heads themselves are not shown in FIGS. 4 and 5, but in FIG. 5 the nozzle 17 for suction of the drilling residues and the conduit 18 which routes them to the ground surface are nevertheless seen.
  • the spacing of the support plates 6 and connection 7 is caused by two rows of hydraulic cylinders 19 interposed respectively with the threaded holes 8 of each of the rows of holes.
  • the jacks 19 are produced directly by drilling the plate 7, these holes opening out on the side of this plate opposite the plate 6. In these holes, are placed pistons 20 which are capable of being displaced by a hydraulic fluid supplied by pipes 21 and 21- 'simultaneously supplying all the jacks 19 of the same row.
  • an extensible rubber skirt 22 is arranged all around the two plates 6 and 7.
  • O-rings 23, 23 ′ are provided in the recessed areas of the plates 6 and 7, these seals being compressed as shown in Figure 4 when the plates 6 ⁇ t 7 are in contact and expanding as shown in Figure 5 when the plates 6 and 7 are spaced from each other.
  • non-return valves 24 are provided to allow pressure balancing when, the two plates 6 and 7 being separated, they are gradually brought back into contact with one another.
  • the device thus described can easily be slaved to the indication of an inclinometer 25 located on the chassis 1 (FIG. 1).
  • the differential speed of the tools 4 and 4 ' is regulated in order to orient the drilling machine in the plane X, while the jacks 19 are supplied with all or nothing by the pipes 21 or 21' in order to play on the verticality in the Y plane.
