Abstract
Un perforateur comprend les composants suivants : une extrémité supérieure; un perforateur relié à celle-ci; un outil hydraulique à actionner relié au perforateur, à l'extrémité opposée à l'extrémité supérieure; et une conduite de liquide qui traverse l'extrémité supérieure jusqu'à l'outil hydraulique, le liquide circulant dans le conduit au-delà du perforateur, jusqu'à l'outil hydraulique, et passant par l'extrémité supérieure pour actionner l'outil hydraulique.
