  • the sensors of the device 8 provide the information adequate to control the correct positioning of the preform in the well. Indeed, this one is flexible since the resin is not polymerized, which does not facilitate the descent into the well. To facilitate this installation, load bars can be added to device 8 in order to best maintain the preform in tension despite friction on the wall of the well.
  • the sensors of the device 8 can be all types of devices which can allow geographic location, or measure deepening according to the gradient pressure or temperature. Temperature indicators can also be used to control the subsequent polymerization operation.
  • a receptacle 11 is fixed under the means 3.
  • the main function of the receptacle 11 is described below.
  • the bottom of the receptacle 11 has an orifice 12 allowing the passage of a at least part of the device 8 outside the preform.

  • Figure 3 shows the lower sealing means 3 equipped with the receptacle 11 linked to means 3, for example by fastening elements 18 which can be sheared under a force determined.
  • Conductors 19 connected to the measurement sensors of the device 8 are continuous with the ground surface by means of connection means 19 (between the head of the device 8 and the seat of the means 3), of conductors 21 included in the means 3, of conductors 22 incorporated into the manufacture of the preform, of the cable 10 already described.
  • Figure 3 shows a tool 23, for example of the "wireline" type constituted by an operating cable 24 (or equivalent) lowered into the casing, a draft head 25 adapted to an additional part 26 fixed on the top of the device 8.
  • FIGS. 4A and 4B show the functional principles and the means specific to the separation of the lower sealing means.
  • separation means 30 are lowered into space inside the casing 2 by the use of maneuvering means 31, for example, rods, tubing, "coil tubing", an electro-hydraulic umbilical, an electric cable.
  • the means 30 are positioned precisely with respect to the sealing means 3 by its support on the seat 6 and possibly using centralizers 32.
  • a rod 33 extends the means 30 by passing to through the orifice 7 of the means 3 and through the opening 12 of the receptacle 11. Fingers 34 lock the rod 33 with the receptacle.
  • Cutting means 35 are carried by arms. retracted during the descent of positioning means 30, expanded during actuation separation means 30. The rotation of the part 36 carrying the means cutting performs the separation of the part 3 of the casing 2.
  • the means 30 comprise means for controlling the spacing cutting arms 35. These means are not shown in FIGS. 4A and 4B.
  • the separation means 30, according to the invention also comprise means for translation of the rod 33 (not illustrated in FIGS. 4A and 4B), after the total cutting of the sealing means 3. The operating principle of these translation means is explained by Figure 4B.
  • the rod 33 has been retracted into the body of the means 30 so as to reassemble the receptacle 11 around the closure means 3 separated from the casing 2.
  • the receptacle plays the role of a case for the closure means 3.
  • the ascent to the surface of the ground, of the receptacle 11, of the separation means 30, can be made by the maneuvering means 31, whatever they may be.
