Title (EN) METHOD AND APPARATUS FOR CONDUCTING EARTH BOREHOLE OPERATIONS USING COILED CASING
(FR) PROCÉDÉ ET APPAREIL POUR CONDUIRE DES OPÉRATIONS DE FORAGE DANS LE SOL EN UTILISANT UNE GAINE SPIRALÉE
Abstract:
(EN) A method and apparatus for conducting earth borehole operations including a reel of continuous coiled casing, and an injector for moving the coiled casing. The bottomhole assembly including at least a motor and a bit connected to the free end of the coiled casing, and injected into the earth while circulating fluid through the coiled casing to form a drilled earth borehole having a borehole wall. The coiled casing drill string may be retrieved from the borehole, the bottomhole assembly removed, and the coiled casing again injected into the borehole, then suspended from a wellhead assembly. After severing the coiled casing, a bonding agent such as a cementitious material may be injected into the suspended coiled casing and into the annulus between the coiled casing and the borehole.
(FR) La présente invention concerne un procédé et un appareil pour conduire des opérations de forage dans le sol comprenant une bobine (28) de gaine spiralée continue (30), et un injecteur (20) pour déplacer la gaine spiralée. L’ensemble fond de trou comprenant au moins un moteur (54) et un trépan (56) est relié à l’extrémité libre de la gaine spiralée, et injecté dans le sol tout en faisant circuler un liquide à travers la gaine spiralée pour former un forage dans le sol ayant une paroi de forage. Le train de tiges de forage de gaine spiralée peut être extrait du forage, l’ensemble fond de trou enlevé, et la gaine spiralée réinjectée dans le forage, puis suspendue à partir d’un ensemble de tête de puits. Après séparation de la gaine spiralée, un agent de liaison tel qu’un matériau cimentaire peut être injecté dans la gaine spiralée suspendue et dans l’anneau entre la gaine spiralée et le forage.
