Claims
- 1. The method of field assembly of a selected number of shaped charges in a well casing perforating gun, comprising the steps of:
- (1) selecting an extruded polygonal carrier strip having N faces where N is an even number greater than 4 and N/2 equals the desired number of perforations at any horizontal level;
- (2) forming shaped charge container mounting holes in vertically spaced relation in each planar side of the polygonal carrier with each horizontally aligned group of mounting holes being angularly spaced from the vertically adjacent horizontal group of mounting holes by 360.degree./N;
- (3) inserting shaped charge containers in the mounting holes;
- (4) inserting the polygonal carrier and shaped charge containers in a tubular housing connectable to a work string.
- 2. The method of field assembly of a selected number of shaped charges in a well perforating gun, comprising the steps of;
- (1) selecting an extruded tubular polygonal carrier strip having N faces where N is an even number greater than 4 and where N/2 equals the desired number of perforations at any horizontal level;
- (2) forming shaped charge container mounting holes in vertically spaced relation in each planar side of the polygonal carrier with each horizontally aligned group of mounting holes being angularly spaced from the vertically adjacent horizontal group of mounting holes by 360.degree./N;
- (3) inserting shaped charge containers in the mounting holes with peripheral flanges on the outer ends of the containers being respectively abuttable with the outer faces of the polygonal carrier and the inner ends of the containers defining a central passage;
- (4) inserting a primer cord in the central passage;
- (5) inserting the polygonal carrier in a tubular housing connectable to a work string; and
- (6) closing the upper end of the tubular housing with an impact actuated detonator disposed adjacent a portion of the primer cord.
