METHOD OF ELECTRIC FIRING AT SHOOTING-FIRING OPERATIONS IN OIL AND GAS WELLS Russian patent published in 1998 - IPC

Abstract RU 2110763 C1

FIELD: applicable in oil and gas industries at shooting-firing operations. SUBSTANCE: filament of filament bridge 1 is warmed up by current transformed in the device. The heated filament actuates the primary charge in the form of highly thermal fuel compound with exothermic self-accelerating combustion. The obtained heat jet actuates the main high-explosive charge. Resistance of the filament bridge filament is selected from the condition of obtaining of temperature of its heating by commercial voltages below the ignition temperature of the high- temperature fuel compound. EFFECT: facilitated procedure. 2 cl, 1 dwg
