Definitions

  • the present invention relates to a drilling installation rotary head comprising means for correcting the trajectory of the head and in particular verticality correction means when the realized drilling is vertical.
  • the present invention relates to such drilling rig that can be controlled automatically, in that concerning the correction of the possible errors of trajectory of the drilling and in particular of verticality.
  • drilling may be required non-vertical, for example, boreholes with all their depth an inclination noted relative to the vertical or Drilling with several portions, each portion having a own inclination with respect to the vertical. In these situations, it is important that the borehole is tilted or tilted defined by the specifications of the book.
  • FIG. 1 there is shown a type of installation known drilling rotary cutting head.
  • the drilling 10 in progress with its casing 12.
  • a head 16 for setting rotation and displacement in translation of the cutting head.
  • the head of rotation and displacement 16 is connected to the cutting tool 18 by a train of rotating rods 20.
  • the drill string 20 is preferably equipped with stabilizing fins such as 22 which ensure a certain centering of the drill string 20 in the borehole.
  • the lower end 20a of the drill string is connected to the cutting tool 18 via two stabilizing drums 24 and 26. Although heard, there could be only one stabilizing drum. In the following the description, the stabilizing drums 24 or 26 will be called “Stabilizers”.
  • Stabilizing drums 24 or 26 are parts constituted by an outer cylindrical skirt whose diameter is slightly lower than that of the cutting tool 18 but much greater than that of the drill string. As will be explained in more detail later, the stabilizer 24 or 26 is freely rotatably mounted around of the drill string 20 but immobilized in translation. The drum or drums the stabilizers 24 or 26 allow (s) to ensure a certain orientation or trajectory to the cutting tool 18. However, even with the presence of these stabilizers, the path of the cutting tool can not be the most often provided with the required tolerance.
  • the stems have a diameter of 200 to 400 millimeters and the diameter of the drilling is at least 1000 millimeters and most often at least 1500 millimeters.
  • the diameter of the stabilizing drums is also from minus 1,000 to 1,500 millimeters and therefore at least three times greater than that of the stems.
  • An object of the present invention is to provide an installation rotary cutting head of the type described in particular with reference in FIG. 1 but which comprises path correction means tool to respect the desired theoretical trajectory.
  • skate is a part of the lateral wall of the stabilizer, it can fully fulfill its role guidance outside the error correction phases of trajectory.
  • the means of angular orientation of the pad comprise first stop means, integral in rotation, of said stabilizer and second means forming a stop integral in rotation with the drill string and mobile in relation to the drill string to take a first active position in which the first and second means forming stop can cooperate to transmit the rotation of the drill string stabilizer audit.
  • said second means forming an abutment include an orientation cylinder whose body is attached to the train of rods and whose rod is movable parallel to the axis of the drill string. In position, the end of the rod of said cylinder is able to cooperate in rotation with the first means forming a stop.
  • the stabilizer 40 consists essentially of a wall external cylindrical 42 of axis X, X '.
  • the side wall 42 is completed by two annular end portions 44 and 45.
  • the stabilizer 40 also comprises in simplified manner an axial sleeve 46 which is engaged around the rods 20 of the drill string. This sleeve is connected mechanically to the side wall 42 for example by radial arms not shown in the figures.
  • the rod 20 on which is mounted the stabilizer 40 has two rings ring rings 48 and 50 which act as a stop to limit the possibilities of translational movement of the stabilizer 40 along the 20.
  • the stabilizer 40 is free in rotation around the rod 20.
  • part of the side wall 42 of the stabilizer 40 constitutes a separate part 52 which is therefore in the form of a portion of cylindrical surface.
  • This separate portion 52 which forms a bearing pad on the borehole wall is mounted movable relative to the rest of the stabilizer by means of displacement cylinders by example the four cylinders referenced 54 in the figures.
  • These cylinders preferably hydraulic, have a body 55 which is secured by any means of the main part of the stabilizer 40 and whose ends 56a of the rods 56 are integral with the shoe 52 also by any suitable way.
  • the rods 56 of the jacks 54 can move in planes orthogonal to the axis X, X 'and in parallel directions y, y' at the median plane P, P 'of the stabilizer.
  • the pad 52 can be moved to using the cylinders 54 between a retracted position shown in Figure 2B in which the shoe 52 constitutes a continuity of the lateral wall 42 of the stabilizer itself and an output position represented in dotted lines in Figure 2B.
  • the pad 52 In this extended position, the pad 52 is applied with pressure against the wall of the borehole or against the casing when provided. It is understood that this action of the pad 52 against the wall of the borehole transmits a force to the drill string 20 and thus to the axis of rotation of the cutting tool 18 to change the path of the cutting tool and correct the axis of the drilling.
  • This orientation of the shoe 52 that is to say the stabilizer 40 is obtained by making a temporary mechanical connection in rotation between the drill string and the stabilizer 40.
  • this temporary link is made, by controlling the rotation of the train of stems from a predetermined angle, the same rotation is stabilizer 40 and thus the support pad 52.
  • the mechanical connection between the drill string and the stabilizer is interrupted. The rotary cutting tool is then restarted. The action of the pad 52 on the tool makes it possible to correct the error of trajectory.
  • the orientation cylinder 60 is a hydraulic cylinder double effect. We can thus use the same liquid supply under pressure for the cylinders 54 which will be described later a mode preferred embodiment of their diet.
  • FIGS. 2A and 2B there is also shown schematically the control of the jacks 54 for moving the 52.
  • the supply of liquid under pressure is achieved through a pipe related to 20.
  • the rod 20 on which the stabilizer 40 is mounted is equipped of a rotary joint 70.
  • This rotary joint comprises a first part 72 secured to the rod 20 and connected to the liquid supply line under pressure and a mobile part 74.
  • This mobile part 74 is equipped with a pipe 76 which enters the stabilizer 40.
  • the pipe 76 is divided in four feed lines such as 78 to feed each jacks 54.
  • the initial orientation of the support pad 52 is performed by the temporary mechanical connection in rotation resulting from the action of the rod 64 of the steering cylinder 60 on the mechanical stop 66 secured to the stabilizer 40.
  • FIG. 3 is a simplified representation of a variant embodiment in which the temporary joining in rotation always includes the orientation cylinder 60 but it can cooperate in output position with a mechanical stop 80 integral in rotation with the mobile part 74 of the rotary joint 70.
  • This mechanical connection can be of any suitable nature and for example by metal rods such as connecting the movable portion 74 of the rotary joint to the wall to the portion upper 44 of the wall of the stabilizer 40.
  • the part rotary joint 70 and the stabilizer 40 it remains the driving link 76 for feeding cylinders 54 in liquid under pressure. In however, the fixed mechanical stop 66 is removed.
  • the orientation jack 60 is a hydraulic cylinder. We would not go out of the invention if this cylinder was pneumatic. In this case, the rods 20 must be equipped with pressurized air supply lines 67 and 68 connected to the anterior chambers 60a and posterior 60b of the cylinder.
  • the organs of control of the correction system are cylinders. They can therefore be controlled automatically and remotely.
  • the stabilizer has a diameter that is at least three times greater than that of rods.
  • the external diameter of the stabilizer is close to that of the rotary cutting tool and therefore that of the drilling.
  • the trajectory correction pad is a part of the side wall of the stabilizer.
