Abstract
Il est décrit un bélier hydraulique pour cisailler un accouplement à chevilles de fond ayant une chambre de piston avec un orifice de fluide supérieur, un orifice de fluide inférieur et une structure de montage portée par la chambre de piston pour monter la chambre de piston dans une position fixe par rapport à un fond de puits de forage, un piston positionné dans la chambre de piston entre lorifice de fluide supérieur et lorifice de fluide inférieur, la chambre de piston étant remplie dun liquide hydraulique au-dessus et en dessous du piston, un connecteur destiné au raccordement à une colonne de fond allongée du fond de puits de forage et une pompe connectée au fluide de pompe dans lorifice de fluide inférieur, la pompe appliquant suffisamment de pression de fluide au piston pour déplacer le piston dune position inférieure à une position relevée et amène le connecteur à appliquer une force de cisaillement à la colonne de fond allongée.
