High density perforating system |
摘要 |
A well perforating apparatus for generating a plurality of material perforating jets. A base has a plurality of recesses or apertures, and a liner is proximate to the base and is indented into each recess or aperture. Explosive charges contact the indented surfaces of the liner to form multiple shaped charges. A detonator activates the explosive material to collapse the liner segments proximate to the explosive charges and to generate a plurality of perforating jets. In one embodiment of the invention, the base initially comprises a planar material that can be formed into a geometric shape for insertion into a cylindrical housing or wellbore. The invention substantially reduces manufacturing costs and is especially useful in permitting a high density shot pattern to be generated by the perforating jets.
