(FR) AGENCEMENT DE SIFFLET DÉVIATEUR/ENSEMBLE DE FOND DE TROU ET PROCÉDÉ
Abstract:
(EN) A whipstock/bottom hole assembly (BHA) arrangement including a whipstock, a BHA, an interconnection arrangement releasably securing the whipstock to the BHA, a fluid flow configuration in the BHA, the configuration directed at the interconnection arrangement. A method for releasing a whipstock from a whipstock/bottom hole assembly (BHA) arrangement as in any prior embodiment including flowing fluid through the fluid configuration, eroding the interconnection arrangement with the fluid, and separating the whipstock from the BHA.
(FR) Un agencement de sifflet déviateur/ensemble de fond de trou (BHA) comprend un sifflet déviateur, un BHA, un agencement d'interconnexion fixant de manière amovible le sifflet déviateur au BHA, une configuration d'écoulement de fluide dans le BHA, la configuration étant dirigée au niveau de l'agencement d'interconnexion. Un procédé de libération d'un sifflet déviateur à partir d'un agencement de sifflet déviateur/ensemble de fond de trou (BHA) selon un mode de réalisation quelconque précédent consiste à faire circuler un fluide à travers la configuration de fluide, à provoquer l'érosion de l'agencement d'interconnexion au moyen du fluide, et à séparer le sifflet déviateur du BHA.
