Definitions

  • the invention relates to a device for unlocking and blocking annular safety shutters (B.O.P.) for wellbore.
  • Document US-A-4 398 598 describes a device for loosening an annular shutter comprising a frame connectable to the shutter and two jacks linked in an articulated manner on the one hand to an upper plate capable of being fixed on the head of the shutter and on the other hand to the frame so that the actuation of the cylinders biases the head of the shutter.
  • the device is not designed for a tightening operation
  • the object of the invention is to create a device for loosening and tightening well shutter blocks guaranteeing maximum work safety and at the same time allowing significant time savings.
  • the invention relates to a device according to claim 1 appended.
  • the jacks are arranged essentially parallel to the jack-carrying arm and linked to the latter in an articulated manner by hinges;
  • the base plate can be secured to a platform carrying a connector for the central guide; on its underside, the base plate can be provided with support legs and a stiffening frame.
  • the device according to the invention allows a significant reduction in the working time necessary for loosening or tightening the well shutter block. At the same time, the risk of accident and damage to the equipment used is reduced.
  • Another advantage of the invention resides in the fact that it is no longer necessary to assemble on site the loosening device and tightening of the well shutter block, but that it is transportable and can be mounted for example on another borehole sleeve.
  • the seat frame 10 shown in FIGS. 1, 1a and 1b is composed of a base plate 11 secured to a platform 11a.
  • the base plate 11 is reinforced, on its underside, by a stiffening frame 14 and provided with support legs 13. With a view to increasing the bearing surface of the support legs 13, these are provided, at their free ends, of support plates 13a.
  • a male slide 12 is arranged in a substantially vertical manner.
  • the slide 12 consists of a double T profile held in position by a lateral spacer 12a.
  • the platform 11a secured to the base plate 11 is substantially circular in shape and provided, in the center, with a connector 15.
  • the connector 15 is provided with a thread 15a into which the tubular central guide shown in detail in Figures 2 and 2a can be screwed.
  • the guide 16 comprises an envelope 16a enclosing an inner tube 17.
  • the free lower end of the inner tube 17 is provided with a male thread 17a capable of cooperating with the female thread 15a of the connector 15.
  • the upper plate 19 ( Figures 3, 3a) is provided with a central coupling bore 21. Reservations 20 are provided concentrically with the central coupling bore 21, these housing bores being reinforced by reinforcement flanges 20a.
  • a guide pin 26, integral with a jack-carrying arm 22 shown in Figures 4 and 4a can be introduced to cooperate with said bore.
  • the arm 22 has a longitudinal extent covering almost the total length of the base plate 11, up to the area of the platform 11a and forms with the slide 12 a bracket.
  • the guide pin 26 is fixed at a free end of the arm 22 to the underside of the latter.
  • the free end of the arm 22 opposite the guide pin 26 is provided with a head element 22a in which is provided a female slide 24 covered by a slide flange 23.
  • the female slide 24 is also formed in double T.
  • connection eyelets 27 are provided, as shown in FIG. 5, with hinge articulation bores 34a corresponding to the hinge articulation bores 34 in the connection eyelets.
  • the jacks 29 are provided with connecting rods 32 provided at their free ends with jack heads 30. At their lower faces, these jack heads 30 are provided with shoes 35 which can be brought into action relationship with the reservations 20 in the upper plate 19.
  • the operation of the device which has just been described is indicated in the following: to block or unblock a safety shutter, the shutter is fixed on the base plate 11 comprising the slide 12, on which is positioned at the desired height the arm 22 by its slide 24. The height is chosen according to the height of the well shutter block 16 to be introduced.
  • the upper plate 19 On the shutter, the upper plate 19 is placed, which by means of coupling fittings is fixed to the shutter.
  • the guide pin 26 provided on the underside of the arm 22 engages in the central bore 21 of the upper plate 19 of which it guarantees the concentricity.
  • the hydraulic drive jacks 29 arranged parallel to the arm 22 engage, with their shoes 35, in the reservations 20 of the plate 19. By means of opposite forces deployed by the jacks 29 and acting one in traction, l 'other in compression, the plate 19 and, with it the well shutter can be rotated by about half a turn, so as to loosen or tighten it.
  • the cylinders 29 can follow the pivoting movement of the plate 19 and of the reservations 20 in the latter.
  • the shutter can be loosened or tightened without endangering the personnel performing the operation.
