Definitions

  • the present invention relates to a method and a system making it possible to carry out measurements or / and interventions in a well at the level of the surrounding formations, and more particularly measurements of noise or vibrations for which the instruments must be mechanically decoupled from the casing by which mechanical waves are transmitted, especially from the surface.
  • the measurements carried out can, for example, include the triaxial recording of the noises produced by the rocks thus put under stress.
  • the analysis of the detected vibrations makes it possible to define the orientation of the noise source and consequently the direction of propagation of the fracture. This analysis technique is well known to geophysicists and will not be described here in more detail.
  • the invention is particularly applicable when it is a question of making measurements, such as vibration measurements, at the level of geological formations of a well located in an area, or close to an area of this well or another well where hydraulic fracturing is practiced.
  • the measurements carried out may also include recording the pressure and the background temperature, the measurement (focused or not) of the electrical resistivity of the formations, etc.
  • One of the objects of the invention is to provide a device making it possible to move a measuring or intervention instrument in a well area.
  • French patents FR-2,544,013, 2,564,894, 2,573,472 already know methods and devices making it possible to carry out measurements or / and interventions in a well, an area of which is subjected to hydraulic compression, but the devices and methods previously proposed show certain drawbacks in use such as the imprecision in maneuvering the support of the assembly, therefore of the instruments, the risks of blocking of the support in the casing, in particular because of the W-groove, the involuntary uncoupling between the transmission cable and the support during operation.
  • This system which can be operated remotely from the surface between a first position and a second position distinct from the first comprises in particular a body inside which a support is placed, the body cooperating with the support to ensure movement of the support relative to the body, and having a lower stop of the body, the support being mechanically connected to said set of instruments by a connecting shaft, the system being characterized in that it comprises another stop delimiting together with the stop in the low position the stroke of said support and in that it comprises means for moving the support relative to the body and that this system is devoid of reversible locking means.

  • the securing means may comprise a shearable mechanical part and adapted to dissociate the traction means from the surface by the cable, the support being in abutment on the second stop limiting the travel of said support in the high position.
  • the system may include destructive support locking means in the first position, the means being erased to allow measurement or intervention of the assembly.
  • the support When a first zone in which said assembly is located is hydraulically isolated from a zone external to this first zone, the support may be adapted to cooperate with the body in order to provide a seal and prevent any flow of fluid in one direction or / and in the other direction between the first zone and the external zone.
  • the system may include means making it possible to dampen the movements of the support in the vicinity of the stops.
  • the compression zone can be delimited by means of at least one expandable annular sealing member placed between the casing and the wall and depending on whether the set is not or is located in said zone, the zone in which the set of instruments is located is isolated or not isolated compression.
