Perforating charge carrier and method of assembly for same

A tubular charge holder assembly for a perforating gun comprising:

• a tube having a plurality of forward openings and a plurality of corresponding rearward openings;
• a plurality of shaped charges, each having a forward end and a rearward end and each of said shaped charges located within said tube and positioned such that said forward end is proximate to one of said forward openings and said rearward end is proximate to said corresponding rearward opening of said tube;
• and
• a clip at least partially surrounding an exterior surface of said tube and positioned proximate each of said shaped charges for securing each of said shaped charges within said tube.

A clip for holding a shaped perforating charge,

• said charge having a forward rim on a forward end and a rear face on a rearward end of said shaped charge,
• within a tubular charge holder used in a perforating gun, said tubular charge holder having a plurality of forward openings and a plurality of corresponding rearward openings, wherein each of said forward openings is larger than each of said rearward openings,
• such that said forward rim is proximate to a forward opening and said rear face is proximate to a rearward opening in said tubular charge holder,
• and for securing a detonator cord to a rear face of a perforating charge,
• said clip comprising:
• a substantially semi-circular body at least partially surrounding an exterior surface of said tubular charge holder and positioned proximate said shaped charge;
• said body having a first end that affixes to a first position on a forward rim of said shaped charge and a second end that affixes to a second position on said forward rim of said shaped charge.

A tubular charge holder assembly for a perforating gun comprising:

• a tube having a plurality of forward openings and a plurality of corresponding rearward openings;
• a plurality of shaped charges, each having a forward end and a rearward end, said rearward end having a rear face, each of said shaped charges located within said tube and positioned such that said forward end is proximate to one of said forward openings and said rearward end is proximate to said corresponding rearward opening of said tube;
• a detonating cord positioned proximate said rearward face of the shaped charge;
• and
• a clip at least partially surrounding an exterior surface of said tube and positioned proximate each of said shaped charges for aligning said detonating cord with said rear face of each of said shaped charges within said tube.

A method of aligning a detonating cord with a rear face of a detonating charge comprising the steps of:

• positioning a shaped charge within a tube such that a rim of a front face of said shaped charge extends at least partially out of a forward opening of said tube and a rear face extends at least partially out of a rear opening of said tube;
• positioning a detonating cord proximate to the rear face of a said shaped charge;
• locating said detonating cord within a retainer on a clip;
• and
• positioning said clip on said tube at least partially surrounding said tube such that said detonating cord is located proximate said rear face of said shaped charge.
