The present invention relates to an apparatus and method for using that apparatus to orient a perforating gun (41) or system to minimize or eliminate the damage that may be caused to exterior control conduits, conductors, devices or to adjacent interior well control lines. The perforating gun (41) or system is attached to a orienting mandrel (99), which has a resilient cam (120) or guide that engages an orienting channel (15) formed on the interior of a specially fabricated tubular member (10). The tubular member (10) is appropriately spaced and properly oriented in relation to the perforating system (41) blast thereby allowing attachement of lines, conduits or devices (6) in the opposite radial direction from the blast of the perforating system (41).
La présente invention concerne un appareil et un procédé permettant d'orienter un perforateur (41) ou un système de perforation destiné à minimiser ou éliminer les dommages pouvant être occasionnés à des conduits de régulation extérieurs, des tubes conducteurs, des dispositifs ou des lignes de contrôle de puits intérieures et adjacentes. Ledit perforateur (41) ou système est attaché à un mandrin d'orientation (99) doté d'une came résiliante (120) ou d'un guide qui rentre en contact avec un canal d'orientation (15) formé à l'intérieur d'un élément tubulaire spécialement conçu (10). Ledit élément tubulaire (10) est espacé de manière approprié et orienté convenablement par rapport au trou de mine dudit perforateur (41), ce qui permet de fixer des lignes, des conduits ou des dispositifs (6) dans une direction radiale opposée à partir dudit trou du perforateur (41).
