Patent

CA 2587782

Apparatus is disclosed for securing a sonde to the inner wall of a well casing (3). The sonde (2) comprises a clamp (2) expandable from a contracted position to an expanded position in which the clamp can engage the inner wall. The securing apparatus comprises a member (5,6) for releasably engaging with the clamp (2) to hold the clamp in the contracted position; a spring (7) connected to the member such that when the spring is in a compressed state, the member is constrained into engagement with the clamp to hold the clamp in the contracted position; and a mechanism (8,9,10) for holding the spring (7) in its compressed state during a 10 first mode of operation and, in a second mode of operation, for releasing the spring (7) from its compressed state thus disengaging the member (5,6) from the clamp to permit the clamp to expand into its expanded position, the mechanism including a material (11) which in the first mode of operation, is in a solid state and, in the second mode of operation, is in a liquid state.

L'invention porte sur un appareil de fixation d'une sonde à la paroi intérieure du tubage (3) d'un puits. La sonde est munie d'une mâchoire (2) pouvant passer d'une position contractée à une position déployée où elle vient au contact de la paroi intérieure du tubage. L'appareil de fixation comprend: un élément (5,6) agissant réversiblement sur la mâchoire pour la maintenir en position contractée; un ressort (7) relié audit élément, qui, lorsqu'il est comprimé, agit sur l'élément (5,6) pour maintenir la mâchoire en position contractée; et un mécanisme (8,9,10) maintenant le ressort (7) à l'état comprimé dans un premier mode de fonctionnement, et qui, dans un deuxième mode de fonctionnement, relâche le ressort (7), ce qui a pour effet de dégager l'élément (5,6) de la mâchoire qui peut alors se déployer. Le mécanisme comporte par ailleurs un matériau (11) qui se trouve à l'état solide dans le premier mode de fonctionnement, et à l'état liquide dans le deuxième mode de fonctionnement.
