  • **Faciliter l'entretien du puits :** Le bol de tubage permet un accès et un entretien faciles du tendeur de tubage et des équipements associés.

**Maintenance et inspection :**

L'inspection et la maintenance régulières du bol de tubage sont cruciales pour garantir son bon fonctionnement continu et prévenir les problèmes potentiels. Cela implique généralement :

  • **Inspections visuelles :** Inspections visuelles régulières à la recherche de signes de dommages ou d'usure.
  • **Essais de pression :** Essais de pression périodiques pour garantir l'intégrité et l'étanchéité du bol.
  • **Lubrification :** Lubrification régulière des pièces mobiles pour assurer un fonctionnement fluide.

**Conclusion :**

Le bol de tubage peut sembler un composant simple, mais il joue un rôle crucial dans le fonctionnement sûr et efficace des puits de pétrole et de gaz. Sa fonction principale est d'abriter et de soutenir solidement le tendeur de tubage, assurant un écoulement continu et fiable des hydrocarbures vers la surface. Une installation, une maintenance et une inspection adéquates du bol de tubage sont essentielles pour maximiser la production et minimiser les risques potentiels associés aux opérations de tête de puits.
