A perforating apparatus (100) used to perforate a subterranean well. The perforating apparatus (100) includes a generally tubular gun carrier (106) and a charge holder (104) rotatably mounted within the gun carrier (106). At least one shaped charge (102) is mounted in the charge holder (104) and is operable to perforate the well upon detonation. A dynamically adjustable weight system (124) is operably associated to the charge holder (104). The dynamically adjustable weight system (124) is operable to adjust the center of gravity (120) of the charge holder (104) such that gravity will cause the charge holder (104) to rotate within the gun carrier (106) to position the at least one shaped charge (102) in a desired circumferential direction relative to the well prior to perforating.
Cette invention concerne un appareil de perforation (100) utilisé pour perforer un puits souterrain. Cet appareil (100) comprend un canon de forme généralement tubulaire (106) et un tube de chargement (104) monté rotatif dans le canon (106). Au moins une charge façonnée (102) est montée dans le tube de chargement (104) et peut perforer le puits au moment de la détonation. Un système de poids à réglage dynamique (124) est associé de manière fonctionnelle au tube de chargement (104). Le système de poids à réglage dynamique (124) permet de régler le centre de gravité (120) du tube chargement (104) de sorte que la gravité fait tourner le tube de chargement (104) dans le canon (106) et positionne au moins une charge façonnée (102) selon une direction périphérique par rapport au puits avant perforation.
