Slide-in frame for shaped charges
A frame for a shaped charge has a body with a cylindrical configuration, the body having a central passage along an axis thereof and a track extending in a direction parallel to the axis for installing and removing a shaped charge, the track having a snap structure. The frame provides a slide-in snap-in charge receptacle for a shaped charge.
1. A frame for a shaped charge, the frame comprising:
a body with a cylindrical configuration, the body having a central passage along an axis thereof and a track, formed in a side of the body and extending in a direction parallel to the axis, for installing and removing a shaped charge, the track having:
a first end and a second end opposite from the first end in a direction parallel to the axis, the first end being open and the second end being closed; and
a snap structure comprising a protrusion formed along an interior wall of the track, wherein the protrusion extends inward from the interior wall of the track a distance that increases from the first end of the track to a maximum distance at a snap point.
2. The frame of claim 1 , further comprising a self-orienting feature.
3. The frame of claim 1 , wherein a flex groove is formed in the body to allow walls of the track to flex.
4. The frame of claim 3 , wherein the flex groove is parallel to a central axis of the track.
5. The frame of claim 4 , further comprising a plurality of placement protrusions located at the second end of the track.
6. A perforation tool, comprising:
a charge module with a slide-in charge frame that has a snap structure, the slide-in charge frame comprising:
a body with a cylindrical configuration, the body comprising:
a central passage along an axis of the body; and
a track, formed in a side of the body and extending in a direction parallel to the axis, for installing and removing a shaped charge, the track having the snap structure; and
an electrical conductor disposed within the central passage.
7. The perforation tool of claim 6 , wherein the slide-in charge frame further comprises a self-orientation feature.
8. The perforation tool of claim 7 , wherein the snap structure comprises a protrusion formed along an interior wall of the track.
9. The perforation tool of claim 8 , wherein the protrusion forms a snap point along the track.
10. The perforation tool of claim 9 , wherein the protrusion extends a varying distance inward from the interior wall of the track.
11. The perforation tool of claim 10 , wherein the track has a first end and a second end opposite from the first end in a direction parallel to the axis, the first end being open and the second end being closed, and the protrusion extends inward from the interior wall of the track a distance that increases from the first end of the track to a maximum distance at the snap point.
12. The perforation tool of claim 8 , wherein the protrusion extends a varying distance inward from the interior wall of the track.
13. The perforation tool of claim 12 , wherein the track has a first end and a second end opposite from the first end in a direction parallel to the axis, the first end being open and the second end being closed, and the protrusion extends inward from the interior wall of the track a distance that increases from the first end of the track to a maximum distance at a snap point.
14. A frame for a shaped charge, the frame comprising:
a body with a cylindrical configuration, the body having:
a central passage along an axis thereof;
a recess formed in the side of the body to receive a weight body; and
a track, formed in a side of the body and extending in a direction parallel to the axis, for installing and removing a shaped charge, the track having a snap structure; and
an electrical conductor disposed within the central passage such that the body can rotate about the electrical conductor.
15. The frame of claim 14 , wherein the snap structure comprises a protrusion that is formed along an interior wall of the track and that provides a snap point along the track.
16. The frame of claim 15 , wherein the protrusion extends inward from the interior wall of the track a varying distance.
17. The frame of claim 16 , wherein the track has a first end and a second end opposite from the first end in a direction parallel to the axis, the first end being open and the second end being closed, and the protrusion extends inward from the interior wall of the track a distance that increases from the first end of the track to a maximum distance at the snap point.
18. The frame of claim 17 , wherein a flex groove is formed in the body to allow walls of the track to flex.
19. The frame of claim 18 , wherein the flex groove is parallel to a central axis of the track.
20. The frame of claim 14 , further comprising a self-orienting feature.
