Definitions
- FIGS. 2A and 2B illustrate shot patterns obtained by perforating guns shown in FIGS. 1;
- the body 93 of the charge holder 90 may be a substantially solid cylinder.
- a cylinder is considered “solid” if at least twenty five percent of a radius 101 from a center of the passage 94 to the outer surface 91 is formed of a solid material.
- Other suitable embodiments may have solid material forming at least forty percent, at least fifty percent, or at least seventy five percent of the radius 101.
- a "solid" cylinder, as referred to in the present disclosure, is in contrast to a "hollow” cylinder.
- a hollow cylinder has a wall that makes up less than forty percent of the radius 101.
- a conventional tube or pipe is representative of a hollow cylinder.
- the perforating gun train 140 When fired, the perforating gun train 140 creates one or more openings as shown in FIGS. 2 A and / or 2B.
- a detonating device 240 for detonating the explosive 234 is positioned adjacent to the apex 236.
- the apex 236 does not enclose the detonating device 240.
- the apex 236 is shaped to be sufficiently narrow to allow a plurality of shaped charges 70 to be circumferentially arrayed on the same plane around the detonating device 240.
- the detonating surface may be defined by an outer surface. All of the shaped charges 70 have an energetic coupling with this outer surface. While the outer surface may define a circumferential body, the outer surface may also define other geometric shapes such as squares, rectangles, ovals, triangles, etc. Regardless of the geometric shape, there are multiple energetic couplings to such an outer surface. While the apex 236 is shown as a concave surface, the apex 236 may also be flat or have any other geometry.
