Abstract
Apparatus for perforating a well comprised of a closed retrievable carrier formed in an elliptic cylindrical shape and having shaped charge perforating means disposed therein. Upon actuation of the shaped charge perforating means the ellipticity of the carrier is reduced.
Claims15
A shaped charge well perforating carrier which comprises a closed tubular housing adapted to be lowered and raised through tubing in a well bore having at least a portion thereof formed in the shape of an elliptic cylinder so that when shaped charge perforating means disposed therein are detonated, the ellipticity of said elliptic cylindrical portion is reduced.
Apparatus for perforating a well which comprises:
- a closed tubular carrier adapted to be lowered and raised in a well bore, at least a portion of said carrier being of an elliptic cylindrical shape;
- shaped charge perforating means disposed within said elliptic cylindrical portion of said carrier, the perforating axis of said shaped charge means being positioned coincidentally with the long axis of the ellipse defined by the wall of said elliptic cylindrical portion when viewed in transverse cross section so that upon detonation of said shaped charge means and penetration of said wall by the jet formed thereby, the ellipticity of said elliptic cylindrical portion of said carrier is reduced.
Apparatus for perforating a well which comprises:
- a closed tubular carrier adapted to be lowered and raised through tubing disposed in a well bore, the end portions of said carrier being of circular cylindrical shape and at least one portion thereof between said end portions being elliptic cylindrical in shape;
- a plurality of shaped charges disposed within said elliptic cylindrical portion of said carrier, the perforating axes of said shaped charges being positioned coincidentally with the long axis of the ellipse defined by the wall of said elliptic cylindrical portion when viewed in transverse cross section so that upon detonation of said shaped charges and penetration of said wall by the jets formed thereby, the ellipticity of said elliptic cylindrical portion of said carrier is reduced.
