Abstract

L'invention concerne un bouchon pour un forage de puits, ledit bouchon comprenant un mandrin et un élément fixé à la face circonférentielle externe qui coupe le mandrin dans la direction axiale, le mandrin et/ou l'élément étant composés d'un matériau dégradable, de préférence de l'acide polyglycolique, et le rayon de courbure d'une partie pliée variant entre 0,5 et 50 mm. L'invention concerne également un procédé de creusement de puits caractérisé en ce que la totalité ou une partie du bouchon pour un forage de puits se dégrade après que le puits de forage est scellé à l'aide du bouchon pour le forage de puits.
