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 so drilling.
  • the invention provides a device for ensuring the verticality of a perforating machine comprising a suspended chassis on which a drilling head is mounted, characterized in that said drilling head is fixed to a connection plate normally in contact with a support plate secured to the chassis, means being provided for moving the connecting plate from the support plate in a chosen direction.
  • orientation means can be much simpler than those which are necessary in the case of a ball joint.
  • These plates can for example be substantially horizontal.
  • connection 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 the 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 can include a stud through clearance with one of the plates and screwed into the other plate with the interposition of compressible elements.
  • the stud can pass through either the connection 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 with game, either between the two plates.
  • the compressible elements can 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, the drilling head of which comprises a pair of tools with a horizontal axis rotating in opposite directions so that the veritcality of the rig drilling is ensured in the plane of rotation of the tools by adjusting the difference in the speed of rotation of the tools.
  • the head In the transverse direction, the head can be mounted on a connecting member mounted to pivot relative to a support member secured to the chassis 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 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.
  • pairs of tools 4 and 4 ′ By varying the relative speed of rotation of pairs of tools 4 and 4 ′, it is possible to add to the progression of the drilling machine in the plane of rotation of the tools. If, for example, we wish to deflect the drilling rig towards + X ( Figure 2) we rotate the pair of tools 4 'faster than the pair of tools 4.
  • a support plate 6 supporting the drilling head 3 is fixed to the lower part of the chassis 1.
  • Threaded studs 10 are screwed into the threads 8 with clearance through the plate 6 through the holes 9.
  • a stack of Belleville washers 11 is interposed between the head 12 of each stud 10 and the upper surface of the plate 6. This stack is protected on the outside by a rubber sheath 13.
  • 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 fixing on the connection plate 7 of the plate itself secured to a frame 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 cylinders 19 are produced directly by drilling the plate 7, these holes opening 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 in the same row.
  • an extensible rubber skirt 22 is placed 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 FIG. 4 when the plates 6 and 7 are in contact and expanding as shown in FIG. 5 when the plates 6 and 7 are separated from each other.
  • non-return valves 24 are provided to allow the balancing of the presisons 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.
