Title
(EN) EXPANSION TOOL FOR NON-CEMENTED CASING-CASING ANNULUS (CCA) WELLBORES
(FR) OUTIL D'ÉLARGISSEMENT POUR PUITS DE FORAGE NON CIMENTÉS DE TYPE ANNULAIRE ENTRE CUVELAGES (CCA)
Abstract
(EN)
The present invention relates to expansion tools used to centralize a casing-casing annulus in a wellbore. One embodiment provides a method for centralizing an inner casing within an outer casing that includes introducing an expansion tool into the inner casing. The expansion tool has an elongate body 10 having a first force multiplier case 28 coupled to an expansion tool case 29. A piston 30A arranged within the first force multiplier case 28 is actuated to move the piston axially in a first direction within the first force multiplier case. The piston 30A engages a ram 34 arranged within the expansion tool 10, and causes the radial expansion of one or more lug assemblies 36 arranged within the expansion tool case 29. The inner casing 28 is then plastically deformed with the one or more lug assemblies 36 as they expand radially.

La présente invention concerne des outils d'élargissement utilisés pour centrer un annulaire entre cuvelages dans un puits de forage. Un mode de réalisation concerne un procédé de centrage d'un cuvelage intérieur dans un cuvelage extérieur, comportant une étape consistant à introduire un outil d'élargissement dans le cuvelage intérieur. L'outil d'élargissement comporte un corps allongé muni d'une première enveloppe multiplicatrice de force couplée à une enveloppe d'outil d'élargissement. Un piston disposé à l'intérieur de la première enveloppe multiplicatrice de force est actionné pour déplacer axialement le piston dans une première direction à l'intérieur de la première enveloppe multiplicatrice de force. Le piston coopère avec un bélier disposé à l'intérieur de l'outil d'élargissement et provoque l'élargissement radial d'un ou plusieurs ensembles d'ergots disposés à l'intérieur de l'enveloppe d'outil d'élargissement. Le cuvelage intérieur est alors déformé plastiquement à l'aide de l'ensemble ou des ensembles d'ergots à mesure qu'ils s'élargissent radialement.
