Method and apparatus for firing multisection perforating guns
Patent
·
OSTI ID:5352857
The method is described of producing the detonation of shaped charges disposed in plurality of vertically stacked, perforating gun sections for a subterranean well, comprising the steps of: (1) running a primer cord through each gun section adjacent the ignition end of each shaped charge container in the section; (2) securing a booster charge to the top and bottom ends of each primer cord to transmit a detonating force from the bottom of one gun section to the top of the next gun section; (3) positioning a low-deflagration rate detonation-transmitting element in each gun section in parallel relationship to at least a portion of the primer cord with the upper end thereof disposed in proximity to the booster charge of an upwardly adjacent gun section; and (4) connecting the lower end of the detonation-transmitting element to a charge disposed adjacent the primer cord of the lower adjacent gun section, thereby assuring transfer of detonating energy from each gun section to the next adjacent gun section.
