Abstract[English]
A nested pipe string (100) for use in a well includes at least one nested pipe joint comprising an inner tube (10B) nested within an outer tube (10A) so as to define an annular space therebetween. The inner tube and the outer tube each comprises a connector (10A1, 10A2, 10B1, 10B2) at each longitudinal end. At least one centralizer (12) is disposed in the annular space and arranged to separate the inner tube from contact with the outer tube. The string comprises a sub (30) connectable to the at least one nested pipe joint. The sub has a first connector mateable with the connector at one longitudinal end of the outer tube, and a second connector mateable with the connector at a corresponding longitudinal end of the inner tube. The first and second connectors are longitudinally offset from each other whereby the inner tube and the outer tube are separately accessible at a longitudinal end opposed to the sub for separately assembling the inner tube and the outer tube to the sub.[French]
L'invention concerne une chaine de tuyaux emboîtés (100) destiné à être utilisée dans un puits, qui comprend au moins un joint de tuyau emboîté comprenant un tube interne (10B) emboîté à l'intérieur d'un tube externe (10A) de façon à définir un espace annulaire entre eux. Le tube interne et le tube externe comprennent chacun un raccord (10A1, 10A2, 10B1, 10B2) à chaque extrémité longitudinale. Au moins un centreur (12) est placé dans l'espace annulaire et est disposé afin de séparer le tube interne du contact avec le tube externe. La chaîne comprend une réduction (30) pouvant être relié à l'au moins un joint de tuyau emboîté. La réduction comporte un premier raccord pouvant être accouplé au raccord à une extrémité longitudinale du tube externe, et un second raccord pouvant être accouplé au raccord au niveau d'une extrémité longitudinale correspondante du tube interne. Les premier et second raccords sont décalés longitudinalement l'un par rapport à l'autre, le tube interne et le tube externe étant accessibles séparément au niveau d'une extrémité longitudinale opposée au raccord pour assembler séparément le tube interne et le tube externe à la réduction.
