Definitions

  • a tubular body (1) provided with an axial cavity (2), a hollow piston (8) capable of sliding in said axial cavity and subjected to variable differential hydraulic pressures, and
  • the piston immobilized by the activation device is subjected to a differential pressure that acts on the piston up or down.
  • the activation device provides a tubular extension extending the piston. The end of this extension is held fixed in a tubular sleeve by shear pins. The sleeve rests on a ring forming stop and attached to the tubular body of the tool.
  • This stop prevents the movement of the piston subjected to a differential pressure and thus producing a tensile force on the tubular sleeve, as long as this pressure remains below a predetermined threshold.
  • the shear pins are calibrated so that a pulling force of the piston greater than the aforesaid threshold causes a shear of the pins and releases the hollow piston which can then slide in the axial cavity of the tubular body of the tool. In the case of a widening tool, the piston turned motor then allows the deployment of cutting arms.
  • the calibrated value of the shear pins is a compromise between, on the one hand, the limit of use of the tool in its dormant mode, that is to say when the hollow piston is not activated, and the limit of the maximum acceptable pressure by the tool or available from the drilling pumps.
  • the caliber of the shear pins is expected as high as possible. Shearing is caused by temporary plugging of the tubular sleeve by a ball and / or by a very large increase in the pressure of the drilling muds. The substantial energy stored by the motor piston must then be dissipated upon release of the piston caused by breakage of the pins. The resulting shock can cause deformations of parts and alter the subsequent operation of the tool.
  • the present invention aims to develop an activation device that is not subject to the risk of accidental activation of the hollow piston and that allows selective activation thereof without significant release of energy so as to release the hollow piston in the axial cavity of the drilling tool, always adequate.
  • safety measures will be provided to prevent the movement of the parts of the tool is prevented or hampered by drilling muds.
  • a trigger element integral with the hollow piston which is displaceable from an immobilization position of the hollow piston, in which the trigger element is held in abutment, against said differential pressures, against a support of the tubular body, towards a position in which the trigger element does not abut against said support and releases the hollow piston,
  • a tubular expansion sleeve of the trigger element which, in said position of immobilization of said trigger element, is connected to the hollow piston by at least one shear pin and prevents movement of the trigger element from its position immobilizing the hollow piston at its erasure position, and
  • a means for temporarily closing the tubular expansion sleeve which, in the closed position, causes a rise in hydraulic pressure on the tubular sleeve, above a predetermined threshold where shear occurs in said at least one pin. shearing, and a sliding of the tubular expansion sleeve in a release position allowing a displacement of the trigger element from its immobilization position of the hollow piston to its erasing position. It can be seen that, in the dormant mode of the tool, the tensile forces exerted by the hollow piston under the action of a differential pressure are not directly transmitted to the shear pins of the activation device.
  • the trigger element that holds the immobilized hollow piston, by pressing on a fixed ring, integral with the tubular body of the tool, the trigger element and the support being in no way intended to to be broken during use.
  • a hydraulic pressure can not be applied on the sleeve when it is closed.
  • a selective activation of the piston because it can take place only by a desired closure of the sleeve, which is controlled from the surface.
  • the tubular expansion sleeve is inserted between the trigger element integral with the hollow piston and an extension of the hollow piston, so as to slide between them after shearing of said at least one pin of shear.
  • the tubular sleeve comprises a first wall portion having a first thickness and a second wall portion having a second thickness less than the first and, in its position of immobilization of the hollow piston, the trigger member is radially supported on said first wall portion of the sleeve tubular and, in its erasing position, it bears radially on said second wall portion.
  • the trigger element is formed of a ring of blades which extend axially around the first part of the tubular sleeve in the immobilization position of the trigger element and which are supported radially on said second portion of the tubular sleeve when the trigger element is in the erasing position.
  • the tubular extension extending the hollow piston is provided with a ring of blades, preferably metal, preferably spring steel.
  • the rigid tubular sleeve is fixedly held at this extension by shear pins. In this position the blades rest on the thick part of the sleeve and are therefore kept apart from one another.
  • the end of these blades which are advantageously thickened and protrude radially outwards, are then in axial abutment against a retaining ring projecting radially inside the tubular body. This arrangement prevents any movement of the piston and the tool is kept in its dormant mode.
  • the temporary sealing means is a ball launched into said axial cavity, the tubular expansion sleeve comprising a seat for receiving this ball and lateral openings to restore a flow of hydraulic fluid when the tubular sleeve is in its release position.
  • a hydraulic pressure obtained by closing the passage of the drilling muds by means of said ball exerts a force on the sleeve.
  • This effort which can be minimal, causes shearing of the shear pins and releases the sleeve that can be released.
  • the blades of the trigger element are then in front of the thinned portion of the sleeve and they can flex radially inwards, for example under a radial thrust of the retaining ring or under the action of an elastic restoring force. In this bent position, the blades can slide inside the retaining ring under the action of the tension of the released hollow piston.
  • the tool is then activated.
  • the tool further comprises
  • a cul-de-sac chamber which extends annularly between said tubular body and said hollow piston and / or a tubular extension thereof, through which drilling muds pass, a surface of the hollow piston axially limiting this chamber in ankle -de-sac, first side,
  • annular ring which axially limits the dead-end chamber, on a second side opposite the aforesaid, and which is connected to the tubular body by at least one shear pin,
  • the hollow piston released by erasing said trigger element, being capable of sliding between a first position in which the dead-end chamber has a first volume and a second position in which the dead-end chamber presents a second volume higher than the first, as well as
  • the tool has an annular chamber in cul-de-sac 10 which extends between, on the one hand, the tubular body 1 and, on the other hand, on the other hand, the hollow piston 8 and its tubular extension 13 through which the drilling muds pass.
  • the surface 11 of the piston axially limits the chamber 10, on one side, and, on the opposite side, it is limited by an annular ring 26.
  • This annular ring 26 is connected to the tubular body 1 via at least one shear pin 27.
