Definitions

  • the present invention relates to a device for the submerged drilling of foundations, and more particularly to such a device of the type comprising at least one cutter and a pump for discharging cuttings, and hydraulic motors for driving said cutter and said pump.
  • Such anchoring points capable for example of taking up vertical or horizontal forces of the order of 1000 or 2000 tonnes, require the realization in the ground, under several hundred meters of water, of piles of several square meters of section and several tens of meters in height, and therefore require corresponding holes to be drilled.
  • This device is however limited, at a very great depth, by the weight and the cost of the tubular assembly, and by the power required to ensure the circulation of the hydraulic fluid.
  • the present invention aims to provide a drilling device better suited to very great depths.
  • the subject of the invention is a device for the submerged drilling of foundations, comprising at least one cutter and a cuttings delivery pump, and hydraulic motors for driving said cutter and said pump, characterized in that it comprises a hydraulic turbine capable of operating with the aid of a fluid such as sea water, and a hydraulic power unit driven by said turbine and arranged to supply said hydraulic motors.
  • the device according to the invention consequently comprises its own power installation constituted by the hydraulic power station.
  • Primary energy is very simply supplied from the service vessel in the form, for example, of pressurized seawater, which can be obtained in particular by means of drilling mud pumps with which all vessels are fitted. drilling.
  • the device according to the invention does not require any electrical transfer of power between the surface and the bottom and consequently avoids the use of a high capacity cable which poses problems difficult to solve due to the depth. of proposed operation.
  • the device according to the invention comprises two cutters with horizontal axes rotating in opposite directions.
  • the turbine exhaust is directed to the tools of the cutter to ensure cleaning.
  • the hydraulic power unit can comprise a plurality of hydraulic pumps, for example one per motor, driven by said turbine via a mechanical distribution box.
  • the device according to the invention may comprise a head forming a first distribution box for the supply of said turbine and the delivery of the cuttings.
  • This head can be connected to the body of the device by at least one advance cylinder supplied by said hydraulic unit.
  • the head can also be connected by a two-way pipe to a second connected distribution box, on the one hand to means for supplying the supply fluid to the turbine, and on the other hand to a discharge hose. spoils.
  • FIG. 1 generally shows the drilling rig 1, connected by a drill string 2, of the drill string type, to a service vessel 3 which may for example be a dynamically positioned vessel.
  • the drill string 2 is suspended from the ship by its upper part using an operating winch 4.
  • the ship 3 also carries a pump 5 of the slurry pump type, connected by means of a hose
  • a winch 8 allows the unwinding of an electric cable 9 of low power, making it possible to supply the electrical members, such as the measuring instruments, of the apparatus 1, and another winch 10 allows the unwinding of another cable.
  • the rod train 2 ends at its lower part by a distribution box 13 connected by a two-way pipe 14 to another distribution box 15.
  • the two-way pipe 14 is constituted for example by two concentric tubes.
  • the path of the pipe 14 coming, via the distribution box 13, from the drill string 2, is directed towards a hydraulic turbine 16, via the distribution box 15 and a flexible conduit 17 .
  • the other channel of the pipe 14 is connected at its upper part, via the distribution box 13, to a hose 18 for removing the cuttings and at its lower part, via the distribution box. 15, to a telescopic conduit 19 for discharging the cuttings.
  • the pipe 14 has a length such that the distribution box 13 is located above the guide and blocking means 12 when the device 1 is at the bottom of the borehole.
  • the turbine 16 is provided with a valve 20 controlled by the inlet pressure of the turbine, that is to say the pressure in the duct 17, for regulating the speed of the turbine according to the power demanded.
  • the exhaust 21 of the turbine is directed by a conduit, not shown, to the cutters which will be described below in order to clean the drilling peaks.
  • the rotor of the turbine 16 is connected, by means of a coupling 22, to a mechanical distribution box 23 also serving as a reduction gear, and provided with several outlets capable of driving a set of hydraulic pumps 24.
  • the primary shaft of the distribution box 23 also carries a speed control device 25.
  • the distribution box 23, the pumps 24 and the speed control device 25 are placed in an oil pan 26.
  • the drilling device 1 also comprises two cutters 27 with a horizontal axis and rotating in opposite directions, so as to bring the cuttings back to a suction nozzle 28 connected to a pump 29 for discharging the cuttings.
  • the output of the pump 29 is connected to the discharge conduit 19.
  • the cutters 27 and the pump 29 are each driven by one of the hydraulic motors supplied by hydraulic pumps 24.
  • the distribution box 15 is connected to the body of the device 1 by a hydraulic advance cylinder 30, also supplied by one of the pumps 24.
  • the guide and blocking assembly 12 is composed of a lower structure 31 and an upper structure 32, blocking jaws 33 for the pipe 14 being mounted on the upper structure 32, from which they can be actuated at by means of electric jacks 34 supplied by the cable 11.
  • the lower structure 31 forms two sets of guide surfaces 35 and 36 respectively.
  • the guide surfaces 35 form a re-entry cone making it possible to guide the drilling device 1 in a borehole already partially carried out when, for whatever reason, it has had to be withdrawn therefrom.
  • the guide surfaces 36 cooperate with other guide surfaces 37 provided on the upper structure 32 to ensure, during such reentry, correct repositioning between the lower structures 31 and upper 32.
  • the drilling is carried out by an alternative operation of the jack 30 and the jaws 33, as described in French patent application 8 514 939.
