Perforating gun

Claim 2

A perforating gun comprising: an elongated barrel having a passageway therethrough, a channel member mounted in said passageway having a plurality of spaced charge receiving apertures through the channel web, a shaped charge positioned in at least one of said apertures, and including a projecting portion engaging the channel member adjacent the aperture, a spring clip for engaging the apex of said charge and said channel member to secure said charge in the aperture of said channel member, and means for detonating said charge.

Claim 3

The gun of claim 1 wherein said shaped charge includes a housing hAving a shoulder thereon for engaging a surface of said channel member surrounding said apertures with a portion of said housing extending through said aperture.

Claim 4

The gun of claim 2 wherein said means for retaining said charges in said apertures comprises: a spring clip having flanges engaging said channel member and a strap portion interconnecting said flanges which engages the rear portion of said shaped charge.

Claim 5

The gun of claim 1 wherein said elongated barrel has a plurality of thinned portions in the wall thereof at spaced locations aligned with the mouth of said shaped charges.

Claim 6

The gun of claim 4 wherein said charge carrier member comprises: an elongate structural channel, the web thereof containing said plurality of spaced charge carrying apertures, said structural channel having reinforcing flanges thereon.

Claim 7

The gun of claim 1 wherein the exterior of said housing for said shaped charge and said clip member have cooperative means thereon for forming a first passageway, the gun further comprising: a second passageway containing an explosive leading from said first passageway through said housing to said shaped charge, a charge detonator interconnecting said plurality of said shaped charges through said first passageway.

Claim 8

The gun of claim 1 wherein said spring clip has substantial width and thickness to absorb reactive force of explosion of said shaped charge to protect the inner wall of said barrel in the region of the charge apex.

Claim 9

A perforating gun comprising: an elongated barrel having a passageway therethrough, a channel member mounted in said passageway and including a channel web having a plurality of spaced charge receiving apertures formed through it and flanges extending from the web in a predetermined direction, a shaped charge positioned in at least one of said apertures and having an apex and a mouth facing in the same direction as the channel flanges, a spring clip for engaging the apex of said shaped charge and including flanges for retentively engaging the flanges of said channel member to secure said charge in the aperture of said channel member, and means for detonating said charge.

Claim 10

A perforating gun comprising: an elongated barrel having a passageway therethrough, a channel member mounted in said passageway and including a channel web having a plurality of spaced charge receiving apertures formed through it and flanges extending from the web in a predetermined direction, a shaped charge positioned in at least one of said apertures and having an apex and a mouth facing in the same direction as the channel flanges, a spring clip for engaging the apex of said shaped charge and including flanges for retentively engaging the flanges of said channel member to secure said charge in the aperture of said channel member, and means for detonating said charge.

Claim 11

A perforating gun comprising: an elongated barrel having a passageway therethrough, a channel member mounted in said passageway and including a channel web having a plurality of spaced charge receiving apertures formed through it and a pair of flanges extending in a predetermined direction, a shaped charge positioned in at least one of said apertures and including an apex facing in the predetermined direction, a spring clip for engaging the apex of said charge and including flanges for engaging the surface of the channel web opposite the flanges to secure the charge in the aperture of the channel member, spacing means interposed between said shaped charge and the channel web, and means for detonating the charge.

Claim 12

A perforating gun comprising: an elongated barrel having a passageway therethrough, a channel member mounted in said passageway and including a channel web having a plurality of spaced charge receiving apertures formed through it and a pair of flanges extending in a predetermined direction, a shaped charge positioned in at least one of said apertures and including an apex facing in the predetermined direction, a spring clip for engaging the apex of said charge and including flanges for engaging the surface of the channel web opposite the flanges to secure the charge in the aperture of the channel member, spacing means interposed between said shaped charge and the channel web, and means for detonating the charge.

Claim 13

The perforating gun according to claim 9 wherein the shaped charge includes a shoulder and wherein the spacing means comprises a resilient O-ring positioned between the shoulder and the surface of the channel web facing in the direction of the flanges.
