Abstract

Il est décrit un appareil de bouchon de fracturation amélioré servant à installer un bouchon dans un fond de puits. Selon une réalisation, lappareil comprend un élément conique interne ayant de première et deuxième extrémités et un diamètre extérieur croissant à partir de la première extrémité. Lappareil comprend également un manchon extérieur expansible ayant de première et deuxième extrémités, laquelle première extrémité lui permet, grâce à sa conception, de recevoir la première extrémité de lélément conique interne, et laquelle deuxième extrémité comprend plusieurs doigts joints à leurs bouts à des points de rupture prédéterminés. Dès que la première extrémité de lélément conique entre plus profondément dans le manchon extérieur expansible, les doigts de ce dernier se rompent à leurs bouts aux points de rupture prédéterminés et sallongent vers lextérieur de manière à engager une surface de fond de puits.
