Definitions

  • the present application is a division of the initial application EP-A-0.294.252.
  • the present invention relates to equipment for a drill string, such as a drill string, comprising a side window connection for the passage of a cable from the inside to the outside of the rods, with hydraulic sealing around the cable.
  • the body can be adapted to move the clamping element during the translation of the body.
  • the means for immobilizing the anchoring member and the cable can be released by remote control.
  • the release of the immobilization means may be obtained under the action of a traction exerted by the cable from the surface.
  • the immobilization means may include a shearable pin beyond a certain stress threshold.
  • the surface of the anchoring element may be crenellated and include at least one notch and the stop may be adapted to penetrate into the notch when the translation is carried out.
  • the reference 1 represents the connection with side window screwed by its upper 1a and lower 1b ends respectively to an upper element 2 and a lower element 3 of the drill string.
  • This connector has a side window 5 allowing the passage of an electric cable 4 from the outside to the inside of the rods, by relying on two guide rollers 6a and 6b.
  • This cable is, for example, of a type used for logs or interventions carried out according to the technique described in patent FR-A-2,501,777 and its aforementioned additions.
  • the upper end 1a may include a plug allowing the upper element 2 to be closed.
  • the member 8 seals around the cable 4 between a zone 9 inside the fitting 1 and the outside of the fitting.
  • the inner zone 9 opens into the lower part of the drill string, through the lower element 3.
  • This inner zone 9 is in communication with a lateral opening 10 located in the connector and which can be connected to an installation of pumping adapted in particular to produce a circulation of fluid with a view to displacing tools and measuring or intervention instruments connected or not connected to the cable 4.
  • One of these instruments may be a load bar comprising an electrical connector adapted to cooperate with another complementary electrical connector.
  • the member 8 also ensures the anchoring of the cable 4 to said connector 1.
  • the means of the connector 1 specifically intended for sealing and carried by the member 8 comprise two complementary parts (8a, 8b) assembled by screws 7 and adapted to be placed around the cable (4) and to be watertight at the passage of fluid from the inside to the outside and vice versa.
  • the interior of these two parts is bored so as to be able to place deformable rings 16 and a compression ring 17 therein and to keep these rings locked in a direction. All these rings, or some of them only, are split so that they can be put in place once the cable passes through the fitting 1.
  • a nut 18, comprising a lateral opening for its introduction around the cable 4 and on the member 8, makes it possible to compress the deformable washers 16 so as to produce a seal.
  • the assembly suitable for producing the internal sealing means and comprising the two complementary parts 8a, 8b, the deformable washers 16, the compression washer 17 with half-moon and, the nut 18 corresponds to the cable gland generally retained for this usage.
  • the external sealing means comprise the two complementary parts or body 8a, 8b cooperating with one or more external seals 14, such as an O-ring, and the internal wall of fitting 1.
  • the anchoring member specifically intended for immobilizing the cable 4 relative to the connector 1 and carried by the member 8 comprises the two complementary parts or body 8a, 8b, and a clamping element 8c actuated by clamping screws 12.
  • One 8b of the complementary parts or body 8a, 8b has a flared recess opening onto the cable 4 and in which the clamping element 8c is positioned which, under the action of the stud screws 12, prevents the cable 4 from move.
  • These screws 12 include sealing means preventing any passage of fluid between their body and the holes in which they are housed.
  • the sealing and anchoring member 8 further comprises a lug 19 cooperating with a groove 20 located in the connector 1, both adapted to allow relative movement when the cable is detached.
  • the member 8 is immobilized relative to the connector 1 by a shearable pin 11 which allows, by its shearing, to release the member 8 in translation when a traction is exerted on the cable 4.
  • the equipment is implemented as follows, while the side entry fitting is accessible, for example when it is close to the surface.
  • the clamping screws act as adjustable stops, but fixed stops could also be used.
  • the cable can be clamped by wedging the anchoring member, or more precisely the clamping member, inside the connector, by axial pressure on said member. , or by self-pinching the cable once the jamming has started.
  • the cable runs freely inside the member 8 and the connector 1, until the cable can be completely removed and thus be able to perform operations, such as unlocking the column, which the presence of the cable would prevent.
  • the clearance surfaces 13 shown in FIGS. 1A and 1B have a slope whose inclination is adapted to increase the clearance between the anchoring element 8c and the pins of the screws 12 when the member 8 follows the movement of the cable printed by a pull on it.
  • the angle alpha between the oriented axes of the translation OT and of the inclined part is an acute angle.
  • the top of this acute angle is oriented towards the bottom of the well, that is to say in the opposite direction to that in which the traction intended to release the cable will be exerted.
  • FIG. 3 represents a second embodiment of the clamping element, in which the release surfaces comprise a part without inclination 13a on which the stud of one of the screws 12 is supported, followed by a part 13b , such that the clearance between the stud and the anchoring element 8c increases suddenly.
  • the surface therefore assumes a notched shape 13a, 13b, where the vertices 13a correspond to the clamping positions of the clamping element 8c, and where the notches 13b correspond to the cable release positions.
  • the inclined release surfaces allow both the release of the cable after a slight displacement of the member 8 and greater precision in the tensile threshold to be exerted to shear the pin 11.
  • the axes of the screws 12 can be substantially perpendicular to the clearance surfaces 13.
  • the surface area of the studs in contact with the inclined parts of the clearance surface 13, or in contact with the parts 13a according to the second embodiment, will be as large as possible.
  • This reduction in diameter allows a cable to run along the upper elements of the drill string to the upper end of the well, especially when the lower and upper elements of the drill string are offset.
  • An advantageous offset can be obtained when the lower and upper elements have a substantially common generator.
  • Hoods can be used to apply the cable to these upper parts of the drill string.
