CASED PERFORATION TOOLS
A tool (350) includes a main body with one or more segments (354). Each of the one or more segments (354) includes an outer wall (355a/b), an inner volume defined within the outer wall (355a/b) and a pre-perforated spear (352) mounted at the outer wall (355a/b). The tool (350) also includes one or m...

| Zusammenfassung: | A tool (350) includes a main body with one or more segments (354). Each of the one or more segments (354) includes an outer wall (355a/b), an inner volume defined within the outer wall (355a/b) and a pre-perforated spear (352) mounted at the outer wall (355a/b). The tool (350) also includes one or more acoustic transducers (360) which induce sonoluminescence in the inner volume, wherein pressure resulting from the induced sonoluminescence causes the pre-perforated spear (352) to be ejected from the outer wall (355a/b). A related method includes providing such a tool (350), inserting it to a wellbore (302) and ejecting it from the outer wall (355a/b) as noted.
Un outil (350) comprend un corps principal constitué d'un ou plusieurs segments (354). Chacun des segments (354) comprend une paroi externe (355a/b), un volume interne défini à l'intérieur de la paroi externe (355a/b) et un harpon pré-perforé (352) monté au niveau de la paroi externe (355a/b). L'outil (350) comprend également un ou plusieurs transducteurs acoustiques (360) qui induisent une sonoluminescence dans le volume interne, la pression résultant de la sonoluminescence induite entraînant l'éjection du harpon pré-perforé (352) de la paroi externe (355a/b). Un procédé associé comprend la fourniture d'un tel outil (350), son insertion dans un puits de forage (302) et son éjection de la paroi externe (355a/b) comme mentionné. |
