Title (EN) VIBRATION-INDUCED INSTALLATION OF WELLBORE CASING
(FR) INSTALLATION INDUITE PAR VIBRATION D'UN TUBAGE DE PUITS DE FORAGE
Abstract:
(EN) An unbalanced sub-assembly includes a turbine and a shaft coupled to the turbine at a first end of the shaft. The unbalanced sub-assembly is capable of rotating and imparting a vibration to the casing in response to a fluid being passed through the casing. A rupture disc is positioned on one end of the unbalanced sub assembly. The rupture disc is configured to rupture above a specified differential pressure threshold caused by fluid flowing through the vibration assembly. The rupture disc is capable of allowing the fluid to bypass the unbalanced sub assembly when the rupture disc is in a ruptured state. The rupture disc directs fluid through the unbalanced sub assembly when the rupture disc is in an un-ruptured state.
(FR) L'invention concerne un sous-ensemble non équilibré comprenant une turbine et un arbre couplé à la turbine, à une première extrémité de l'arbre. Le sous-ensemble non équilibré est susceptible de tourner et de conférer une vibration au tubage, en réponse au passage d'un fluide à travers le tubage. Un disque de rupture est positionné à une extrémité du sous-ensemble non équilibré. Le disque de rupture est conçu pour se rompre au-dessus d'un seuil de pression différentielle spécifié, induit par l'écoulement d'un fluide à travers l'ensemble de vibration. Le disque de rupture est en mesure de permettre au fluide de contourner le sous-ensemble non équilibré lorsque le disque de rupture est dans un état rompu. Le disque de rupture dirige le fluide à travers le sous-ensemble non équilibré lorsque le disque de rupture est dans un état non rompu.
