CA 2635161

A method of forming a downhole connection between tubular strings includes the step of crimping the tubular strings together. The tubular strings may be positioned in the same wellbore, or the tubular strings may be positioned in different intersecting wellbores during the crimping step. One of the tubular strings may be expanded outwardly within the other tubular string prior to the crimping step.

L'invention concerne une méthode de fabrication de raccord de fond de trou entre des colonnes tubulaires, qui consiste à sertir ensemble les colonnes tubulaires. Les colonnes tubulaires pourraient être positionnées dans le même puits de forage, ou les colonnes tubulaires pourraient être positionnées dans différents puits de forage intersectés durant l'étape de sertissage. Une des colonnes tubulaires pourrait être étendue vers l'extérieur à l'intérieur de l'autre colonne tubulaire avant l'étape de sertissage.
