Definitions

  • darts may be pumped downhole along an interior of a tubing string deployed in a wellbore. The dart is moved until it engages and seals against a corresponding seat. After the dart seals against the seat, fluid may be pressurized in the interior of the tubing string above the seat. The pressurized fluid is used to actuate a desired tool. Following actuation, the dart is removed by a suitable removal process, such as milling, to provide a passageway to a lower portion of the wellbore. The passageway may be used for cementing operations, well treatment operations, and/or a variety of additional or other well-related procedures.

Abstract

L'invention concerne une méthodologie et un système facilitant l'exécution d'une opération dans un tubage, tel qu'un tubage de puits de forage. Un support est placé dans le tubage de sorte qu'un objet peut être libéré le long d'un intérieur du tubage pour mise en prise avec le support. L'objet est conçu avec un composant non dégradable, par exemple, un racleur, monté sur une âme dégradable. Dans de nombreuses applications, un fluide peut être utilisé pour déplacer l'objet le long de l'intérieur du tubage et en prise avec le support. À mesure que l'objet se déplace le long de l'intérieur, le racleur est utilisé pour essuyer, par exemple, racler, le matériau depuis une surface intérieure du tubage. Après que l'objet vient en prise avec le support, une pression peut être appliquée le long de l'intérieur du tubage pour actionner un outil souhaité. À l'achèvement de la procédure, l'âme peut être dégradée, par exemple dissoute, et ainsi être éliminée du tubage.
