These means of transmission at their upper end are for example connected to rotating contacts such as 53. Other means of transmission could be used.
  • Patents FR 2 777 594 and FR 2 777 595 in the name of of COMPAGNIE DU SOL describe transmission techniques information using the drill string as a means of transmission.
  • the intermediate station 12 mounted on the platform 24 of the drilling machine receives the measurements made by the different sensors including the verticality error sensor 46 and transmits operating instructions to the motor control circuit 30 and 36, as well as the control circuit 50 of the error correction system 48.
  • the intermediate station 12 is equipped with means of communication schematically in Figure 1A by the circuits transceiver 55 and the antenna 54 to communicate with the radio station.
  • control 14 itself equipped with an antenna 56.
  • intermediate station 12 might not be mounted on the drilling machine itself but disposed close to it.
  • the solution described makes it possible to simplify the wiring between it and the different components of the set of moving 18 of the rod trains.
  • the control station 14 comprises transmission-reception circuits 58 allowing the formatting of information received or information to be transmitted to the intermediate station 12.
  • the command 14 is essentially constituted by a unit of processing 60 associated with memory means 62.
  • the processing unit 60 receives the different measurements made in the drilling machine by the different sensors and detectors and this unit processes this information to deliver feedback control commands of the motors 30 and 36 of the displacement assembly 18 and the control means 50 of the verticality error correction device.
  • the means in memory 62 store, on the one hand, programs to manage the entire drilling machine from the measurements made by the various sensors in particular for the implementation of the possible error correction steps of verticality and, more generally, for the adaptation of the parameters of drilling at the geological conditions encountered and, secondly, possibly data collected during test drilling.
  • Figure 1B shows in more detail the different links that between the sensors and controls present in the the moving assembly of the rods 18 with the intermediate station 12.
  • FIGS. 2A, 2B and 3 we will describe a preferred embodiment of the verticality correction means usable in the installation described in connection with FIG.
  • the rotary drilling head 22 fixed is shown at the lower end 20a of the drill string 20 as well as the correction of verticality error which is generally referred to 48.
  • the verticality correction device 48 is constituted essentially by a support pad 70 which is mounted at a first lever arm end 72.
  • the second end 72a of the arms 72 is pivotally mounted about an axis 74 orthogonal to the vertical axis XX ' of the drill string.
  • the axis 74 is constituted for example by two bearings 74a, 74b aligned and mounted on a first ring 76 which is free to rotate around the lower end 20a of the drill string but secured in translation of it. This result is obtained for example by interposing between the first ring 76 and the drill string of the adapted bearings to the conditions of use.
  • the displacement of the pad 70 is obtained by the pivoting of the arms 72 about the axis 74.
  • This pivoting is controlled by a second ring 78 disposed below the first ring 76, this ring 78 being mounted free in translation on the drill string 20 but integral in rotation thereof.
  • the periphery of the underside 78a of the second ring 78 receives the ends of the rods 80a of cylinders 80 fixed vertically on the upper part 22a of the rotating head of 22.
  • the number of cylinders 80 is determined to allow exercise symmetrically the desired thrust on the second ring 78. jacks 80 thus allow the displacement in translation of the ring 78 the along the rod 20a.
  • the upper face 78b of the second ring 78 preferably comprises a chamfered periphery 82 on which comes in contact with a preferably frustoconical roller 84 rotatably mounted around an axis 86 which is itself secured to the arms 72.
  • a pin 90 secured to the arms 72 penetrates into a blind hole 92 arranged in the lower part 20a of the drill string.
  • the blind hole 92 constitutes an angular reference position for the pad 70 relative to to the vertical axis XX 'of the rotary drilling head.
  • the train of rods is rotated to bring the blind hole 92 next to of the lug 90 so that the pad 70 can resume its position reference.
  • the operation of the error correction system of verticality is as follows: when the processing unit 60 detects that the inclination information of the cutting tool 22 is greater than a threshold predetermined, this activates the error correction program of verticality contained in the memory assembly 62.
  • the drilling tool 22 is stopped and the rotation of the drill string is controlled to bring the verticality correction mechanism 50 in the angular orientation provided by the verticality detector 46.
  • This position can be detected by an angular position detector 100 mounted in the set of moving 18 of the drilling machine next to a crown indexed 102 integral rotation of the drill string.
  • the treatment unit 60 controls the activation of the jacks 80 of the error correction system verticality 48.
  • the pad 70 is disengaged in rotation from the drill string and bears against the wall of the borehole to exert its effect correction and the central unit 60 then controls the re-rotation of the 20. This situation is maintained until the tilt information delivered by the sensor 46 via the station intermediate 12 becomes less than a predetermined value indicating that the verticality error has been corrected.
  • the processing unit 60 controls the stop of the rotation of the drill string and the deactivation cylinders 80 of the verticality correction system.
  • the skate 70 resumes thus its reference reference position and the processing unit 60 then controls the re-rotation of the drill string 20 in the previously defined conditions.
  • the central unit 60 with its programs stored in the memories 62 can also control that the drilling conditions are optimal for the terrain.
  • the central unit can either modify by example the speed of rotation of the tool and its speed of descent in function of data relating to the nature of the terrain stored during drilling test. It may also process information relating to the speed of rotation, speed of descent and force, thrust exerted on the tool to ensure that these three quantities verify drilling optimization criteria in the field encountered. If this is not the case, the central unit 60 can change the speed of rotation or the speed vertical descent.
  • the verticality error detector 46 it can be constituted as follows.
  • Figures 5A and 5B illustrate this detector. It comprises a first inclinometer 104 disposed radially with respect to the tool and a second inclinometer 106 also radial and perpendicular to the first. Both inclinometers are close to the periphery of the tool. The measurements made by both Inclinometers can be used to derive the tilt of the tool and the direction angle of this inclination. Preferably, a second measured after a 180-degree rotation of the tool. This is illustrated Figures 5A and 5B. Also preferably, a gyroscope is provided to identify the angular orientation of the tool to orient later correctly the pad 70 verticality correction.
  • the measurement of verticality made by the sensors 46 is carried out when the rod drilling 22 is stopped.
  • One of the programs stored in the means memory 62 relates to this operation.
  • the processing unit 60 commands the stopping of the train of stems and activation of verticality sensors. He also commands the 180 degrees rotation of the drill string to perform the second measured. If the measured inclination angle is greater than the value predetermined, the verticality correction program described previously is implemented. Otherwise, the tool of drilling 22 is put back into action.
  • the invention also applies to non-vertical drilling.
  • the angle measurements provided by the sensors 46 are compared to the angles defining the path of the tool that must be followed to comply with the specifications of the book. If the difference between the measured angles and the angles defining the trajectory is greater than a predetermined value, the correction system of trajectory, constituted for example by the system 48 represented on the Figures 2A, 2B and 3 is activated.
