Abstract
A perforating gun is disclosed with shaped charges at a preferential orientation. An example includes a gun body and a charge carrier disposed within the gun body. The charge carrier defines a longitudinal carrier axis and has a plurality of axially-spaced charge mounting locations. A plurality of charges are each pivotally mounted to the charge carrier at one of the respective charge mounting locations about a charge pivot axis transverse to the longitudinal carrier axis. The charges may preferentially align in response to gravity so their orientation remains constant throughout a range of inclination of the wellbore.
Claims11
A perforating gun, comprising:
- a gun body;
- a charge carrier disposed within the gun body, the charge carrier defining a longitudinal carrier axis and having a plurality of axially-spaced charge mounting locations;
- and
- one or more charges each pivotally mounted to the charge carrier at one of the respective charge mounting locations, wherein each charge mounting location is disposed about a respective charge pivot axis defined by a corresponding pivot, wherein each charge pivot axis is transverse to the longitudinal carrier axis, and wherein each charge of the one or more charges is configured to pivot about their respective charge pivot axis to maintain a vertical fining orientation, with respect to a direction of gravity in response to gravity.
