Abstract
Un système de colonne montante est présenté servant à fixer de manière amovible un dispositif de contrôle de débit pivotant à lintérieur de la colonne montante en vue du forage hauturier. Le système comprend une section de colonne montante, un dispositif de fixation amovible servant à fixer de manière amovible le dispositif de contrôle de débit pivotant et des éléments de retenue, supérieurs et inférieurs. Les éléments de retenue sont disposés dans la section de colonne montante et limitent axialement le dispositif de retenue de manière axiale entre eux. Au moins un des éléments de retenue est fixé de manière amovible à la paroi interne de la section de colonne montante. Le dispositif de retenue comprend un loquet et un élément de joint servant à engager le mécanisme de contrôle de débit pivotant, qui sont actionnés ensemble de manière hydraulique ou pneumatique.
