摘要 |
The invention relates to a well perforation device comprising a support (25) and encapsulated shaped charges (26) fixed unidirectionally on this support, usually on the back side of a support bar whose front side is to be applied against the casing. Positioning rings (35, 36) are snapped onto the charges (26) at regular intervals along the support (25). These rings have a rounded external surface on which the perforation device can swivel up to a correct balanced position for which the front sides of the charges are applied against the casing (13). |
