Abstract
A energy transfer device (10) is provided that is capable of transferring the energy output from one pyrotechnic device (52) to another device (78) for initiating firing thereof. Device (10) comprises a device housing (12) in which a deformable device insert (14) is received. Device insert (14) comprises a central passageway (34) for transmitting the output from a pyrotechnic device (52), including energy, gasses, and/or solids, to another pyrotechnic device (78). The passageway (34) conducts the pyrotechnic device output to a precise location on the second pyrotechnic device (78) where firing is most effectively initiated. The energy transfer device (10) may be employed as a part of a tool (44) used in well completion operations.
Claims17
A method of igniting a pyrotechnic charge downhole in a well comprising:
- providing a first pyrotechnic device, an energy transfer device, and a second pyrotechnic device, said energy transfer device comprising a metallic body having a forward section, an aft section, and an axial passageway extending therethrough;
- igniting said first pyrotechnic device to detonate an output charge;
- and
- directing at least a portion of the energy from the detonation of said output charge through said axial passageway toward said second pyrotechnic device thereby igniting said second pyrotechnic device,
- wherein said first output charge deforms at least a portion of said energy transfer device forward section resulting in the formation of a constriction in said passageway, and wherein said first output charge results in the generation of hot gases and/or solid material at least a portion of which are directed through said passageway and said constriction toward said second pyrotechnic device.
A method of igniting a pyrotechnic charge downhole in a well comprising:
- providing a first pyrotechnic device, an energy transfer device, and a second pyrotechnic device, said energy transfer device comprising a metallic body having a forward section, an aft section, and an axial passageway extending therethrough;
- igniting said first pyrotechnic device to detonate an output charge;
- and
- directing at least a portion of the energy from the detonation of said output charge through said axial passageway toward said second pyrotechnic device thereby igniting said second pyrotechnic device,
- wherein said body forward section comprises a forward face that is configured to be placed adjacent said first pyrotechnic device so as to receive said at least a portion of the energy from the detonation of said output charge, said forward face being deformable by said at least a portion of the energy from the detonation of said output charge to form a constriction in said passageway.
