Title (EN) LINING OF WELL BORES WITH EXPANDABLE AND CONVENTIONAL LINERS
(FR) PUITS DE FORAGE ÉTROIT
Abstract: front page image
(EN)Reducing the diameter of a well bore has many advantages. To achieve this a subsurface well bore is provided comprising one or more expandable sleeve components, preferably expandable liners (27, 271), each expandable sleeve component being fully overlapped by one or more non expandable sleeve component, preferably conventional liners (28, 29), such that the interior of the well bore is cased entirely by non expandable sleeve components (28, 29). In addition the through holes (34a) for downhole lines can be provided within the well head (34) rather than the tubing hanger (33). As the tubing hanger does not need to provide space for through holes and associated mounting couplings, its diameter can be reduced, thus reducing the internal diameter of the well bore by several inches.
(FR)La réduction du diamètre d’un puits de forage présente de nombreux avantages. Pour l’obtenir, un puits de forage souterrain comprenant un ou plusieurs composants de type expansible, de préférence des chemisages expansibles, est fourni, chaque composant de type manchon expansible étant entièrement recouvert par un ou plusieurs composants de type manchon non expansible, de préférence des chemisages classiques, de telle sorte que l’intérieur du puits de forage soit entièrement tubé avec des composants de type manchon non expansible. En outre, des trous débouchants pour des conduites fond de puits peuvent être disposés à l’intérieur de la tête de puits plus loin que le dispositif de suspension de tubage. Etant donné que le dispositif de suspension de tubage ne nécessite pas de fournir de l’espace pour les trous débouchants et les accouplements de montage associés, son diamètre peut être réduit, ce qui réduit le diamètre intérieur du puits de forage de plusieurs pouces.
