Abstract[English]
A tripping operation is performed during the drilling of a wellbore in a subterranean formation. The tripping operation includes displacing a drilling fluid from a drilling string disposed within the wellbore by flowing an alternative fluid through the drilling string. The drilling fluid is the same type of fluid used when drilling the wellbore. The tripping operation includes displacing the drilling fluid from the wellbore to a terranean surface by flowing the aqueous fluid into the wellbore, and withdrawing the drilling string from the wellbore.[French]
Une opération de déclenchement est effectuée pendant le forage d'un puits de forage dans une formation souterraine. L'opération de déclenchement comprend le déplacement d'un fluide de forage d'une colonne de forage disposée à l'intérieur du puits de forage par écoulement d'un fluide alternatif à travers la colonne de forage. Le fluide de forage est le même type de fluide utilisé lors du forage du puits de forage. L'opération de déclenchement comprend le déplacement du fluide de forage du puits de forage à une surface terrestre par écoulement du fluide aqueux dans le puits de forage, et le retrait de la colonne de forage du puits de forage.
