Patent

CA 2570746

Drilling a well to total depth without tripping the bit out of the hole despite encountering a troublesome zone is made possible by using a memory based composite material delivered with the drill pipe or advanced over it, as needed. The material can be activated as a troublesome zone is encountered and assumes as former configuration that places it in sealing relation to the troublesome zone in the bore hole while spacing it from the drill pipe so as to allow resumption of drilling with the troublesome zone isolated.

L~invention permet de forer un puits à la profondeur totale sans effectuer de va-et-vient du trépan malgré la présence d~une zone délicate à l~aide d~un matériau composite à mémoire accompagnant le train de tiges ou placé devant celui-ci, selon les besoins. Le matériau peut être activé lorsque l~on rencontre une zone délicate et reprend une configuration antérieure le protégeant hermétiquement de la zone délicate dans le trou de sonde tout en l~écartant du train de tiges de façon à reprendre le forage après isolation de la zone délicate.
