Definitions

  • the present invention relates to a drilling installation whose mast is not subjected to compressive stresses.
  • drilling units consisting of a towed or even self-propelled vehicle equipped with a platform provided with a mast along which is slidably mounted a carriage carrying a driving head.
  • This drive head is used to generate the rotation of a rod (or a drill string) whose lower end is provided with excavation means such as, for example, a drill bit.
  • the mast is equipped with one or more pulleys for guiding a link, for example a cable or a chain that comes from a winch carried by the vehicle and which wraps around halyards to form a hoist.
  • a link for example a cable or a chain that comes from a winch carried by the vehicle and which wraps around halyards to form a hoist.
  • this hoist comprises a device for attaching the upper end of the rod (or drill string) for drilling.
  • this attachment element is itself slidably mounted on the mast and is integral with the aforesaid carriage, or even the drive head.
  • the mast must be braced to account for the orientation of the resulting susquite relative to the axis of the mast.
  • the invention is therefore more particularly intended to overcome this drawback by means of an installation of the aforesaid type involving a mast comprising a fixed part on which is slidably mounted a movable structure provided with a fastening head and a rotary drive. a driven member such as a rod or drill string for drilling.
  • this installation is characterized in that the driving of the mobile structure along the fixed part is ensured by means of a mechanism involving at least one linear actuator oriented parallel to the mast, one of whose ends is supported on the fixed part, for example the platform, while the other end carries at least one pulley around which passes at least one link such as, for example, a cable or a chain whose end is secured to the part fixed while the other end is secured to the aforesaid mobile structure.
  • the two strands of the link which extend respectively on either side of the pulley are oriented so that the resultant of the forces exerted on the pulley by the link extends coaxially with the jack.
  • the installation comprises two cylinders arranged symmetrically in a plane passing through the axis of the rods, at least two pulleys respectively mounted on the upper ends of the cylinders and at least two cables passing respectively around said pulleys, these two cables being secured by one of their ends to the aforesaid mobile structure.
  • a single cable flowing around the two aforesaid pulleys may be used in place of the two previously mentioned cables.
  • the two ends of the cable are secured to the fixed part while its central portion can pass around at least one pulley rotatably mounted on the movable structure.
  • the drilling rig 1 is integrated in a trailer of a semi-trailer 2 whose platform constitutes the platform.
  • This plate is equipped with retractable legs each comprising a ground support plate 3, 4 and telescopic columns 5, 6 actuated by hydraulic cylinders so as to obtain a "self-elevating structure on the ground" without substructure.
  • the cylinders In the retracted position, the cylinders are in the retracted state. In this position, the support plates 3, 4 extend above the ground and are optionally folded.
  • the trailer 2 is supported on its wheels 7 and can be coupled to the tractor. In the deployed position of the cylinders, the support plates 3, 4 rest on the ground while the trailer 2 is raised as indicated figure 1 , the wheels 7 being above the ground.
  • the front part of the platform carries the technical elements 8 of the installation in particular, such as the engine (power unit), the compressor, the hydraulic power unit, pumping units and all the control, control and maintenance systems. regulation.
  • the two rear uprights 13, 14 of the fixed part 11 are constituted by tubular elements of square section fixed by their lower parts on the platform by means of clamps.
  • the anterior amounts 15, 16 of the fixed part 11 are, for their part, constituted by tubular elements of square section but of reduced dimensions compared to those of the posterior amounts, these anterior amounts are also fixed on the platform by means of fastening flanges.
  • the posterior uprights 20, 21 of the movable part 12 consist of H-shaped section elements whose parallel wings are situated at a distance slightly greater than the width of one side of the section of the rear uprights 13, 14 of the fixed part 11.
  • the spacing between the uprights 13, 14 is provided so that they engage in the cavities of the uprights 20, 21 facing outwards.
  • Sliding means for example bearings, are provided for reducing the coefficients of friction between pairs of uprights 13, 14 and 20, 21.
  • the uprights 20, 21 of the mobile part 12 each carry at their ends a yoke in which is rotatably mounted at least one pulley P 1 , P 2 .
  • the upper end of this movable part 12 is furthermore equipped with a support and guide element 25 in the form of a half openwork drum for hose reel.
  • This support and guide element is intended to support the hydraulic ducts leading to the hydraulic members supported by the mobile part 12.
  • the bottom of the half drum on which the hydraulic ducts support is constituted by a succession of rotary rollers 26 oriented perpendicularly to the direction of travel of the conduits.
  • the displacements of the mobile part 12 along the fixed part 11 are controlled by two linear cylinders V 1 , V 2 housed in the rear uprights 13, 14 of the fixed part 11.
  • These two cylinders V 1 , V 2 of simple type or double effect, comprise a tubular body 27 with cylindrical bore in which is slidably mounted a piston 28.
  • This piston 28 is itself attached to the end of a coaxial rod 29 longer than the body 27.
  • the lower end of the body 27 is integral with the platform while its upper end is provided with guide means, with sealing of the rod.
  • the upper ends of the rods 29 of the two cylinders V 1 , V 2 are fixed to the upper end of the movable part 12, on the yokes used for rotatably mounting the pulleys P 1 , P 2 .
  • a carriage 30 carrying a fastening and driving head 31 in rotation of the rods 32 for drilling.
  • this carriage 30 comprises two opposed pads 33, 34 which engage in the recesses of the rear uprights 20, 21 opposite each other to the mobile part 12.
  • sliding means for example bearings, are provided to reduce the friction between the pads and the rear uprights 20, 21.
  • the movements of the carriage 30 are controlled by two cables C 1 , C 2 (or pairs of cables) passing respectively around the pulleys P 1 , P 2 .
  • One of the ends of each of these two cables C 1 , C 2 is fixed in one point (eyelets 35, 36) of a corresponding posterior post 13, 14 of the fixed part 11 while the other end comes to attach to the attachment and drive head carried by the truck.
  • the fixing and rotational driving head 31 of the rods 32 comprises a coaxial vertical channel as well as coupling means on which the rods 32 can engage and fix.
  • the platform comprises a circular through hole 37 disposed in line with a recess 38 (here rectangular) provided in the support plate 3.
  • the figure 3 illustrates the operating principle of the previously described installation.
  • these fasteners 35, 36 will be directly provided on the platform, the fixed part of the mast 10 then playing only a guiding role and recovery of the torque generated by the head 31.
  • the speed of movement of the carriage 30 is twice that of the rod 29 of the cylinders V 1 , V 2 .
  • the size of the installation, once the mast folded at 90 ° on the trailer, is limited so as not to exceed the length of the trailer.
  • the overall width of the installation is limited to the road gauge (for example to 3 m for traffic on the European road network) because the support columns 5, 6 (which take the loads of the drilling) are retractable and foldable to fit into the template.
  • the mast could be mounted on a vehicle other than the trailer of a semitrailer, for example a barge.
