发明名称 Apparatus and method to mechanically orient perforating systems in a well
摘要 The present invention relates to an apparatus and method for using that apparatus to orient a perforating gun or system to minimize or eliminate the damage which may be caused to exterior control conduits, conductors or devices, or to adjacent interior well control lines, conduits or tubing by attaching the perforating system to a device which has a resilient cam or guide which engages a slot formed on the interior of a specially fabricated tubular member attached at a spaced distance from the perforating systems blast and which is so oriented as to permit the attachment of the lines or conduits or devices in the opposite radial direction from the blast of the perforating system.
