Abstract

Un outil de fonds de puits sert à perforer un puits de forage. Une vanne de piston coulissant est présente, inclinée pour couvrir les orifices de lançage pendant la descente de loutil. Une garniture compressible peut être présente sous les orifices de lançage et un élément de mâchoire est fourni sous la garniture. Un ensemble de fente en J et de tige permet une configuration à trois positions, nommément une position de descente où la garniture est décomprimée et les orifices de lançage fermés, une position fixe où la garniture est décomprimée et l'élément de mâchoire est engagé de force par friction dans la colonne du puits de forage et une position de lançage où la garniture est comprimée, loutil est descendu au moyen dun fluide abrasif sous pression et la vanne de piston a découvert les orifices de lançage. La vanne de piston peut fonctionner à double action soit, pendant la descente, les orifices déjection sont fermés et un orifice de dérivation est découvert, et en position de lançage, les orifices de lançage sont ouverts et lorifice de dérivation est fermé.
