Title
(EN) HELICALLY WOUND INSERT FOR EXPANDABLE TUBULARS
(FR) INSERT TUBULAIRE EXPANSIBLE EN HELICE
Abstract
(EN)
The present invention provides a connector arrangement for connecting a first tubular to a second tubular. In particular, the present invention relates to a method for connecting tubulars in such a way that the connection is prevented from becoming unmade in response to expansion of the tubulars in a wellbore. More particularly, the present invention provides a tubular connection using a helical or spiral thread insert to seal and maintain mechanical strength in a tubular connection after expansion.
(FR)
L'invention concerne un agencement de connecteur permettant de connecter un premier et un second tube. L'invention concerne, en particulier, un procédé permettant de connecter des tubes de façon à empêcher que la connexion soit défaite en réponse à la dilatation desdits tubes dans le puits de forage. L'invention concerne, plus particulièrement, une connexion tubulaire utilisant un insert fileté en hélice ou en spirale afin de sceller et de maintenir une résistance mécanique dans une connexion tubulaire après expansion.
