DEVICE FOR INITIATION OF OIL WELL PERFORATOR Russian patent published in 2001 - IPC

FIELD: oil well perforation systems, more specifically, systems for transmission of detonating signals from initiating charge of explosive to jet charge of perforation unit for shooting of oil well. SUBSTANCE: device has the first igniting head for formation of the first detonating signal, second igniting head for formation of the second detonating signal, the first means for transmission of the first detonating signal to jet charges. Device has the first partition between the first means of transmission and jet charges. This partition hinders transmission of initiating action of lower order to jet charges. There is the second means for transmission of the second detonating signal to charges. The second means of transmission of the second detonating signal has the second partition which hinders transmission of initiating action of lower order from the second means to charges. The first and second means of transmission of initiating action are isolated from each other. Initiation of one means does not cause initiation of the other means. Claimed device provides for establishment of duplication perforator system with igniting mechanism, and capable of initiation of detonation of jet charges even is cases of failure of lower order in the first initiating charge of explosives and/or detonating cord. EFFECT: higher efficiency. 8 cl, 4 dwg
