Heat resisting and pressure resisting safe electric detonator for oil well

The heat resisting and pressure resisting safe electric detonator is used for explosive charge or blasting cartridge in well perforation, seismic prospecting, etc. and relates to blasting technology. The heat resisting and pressure resisting safe electric detonator has high temperature igniting powder and high temperature explosive for the high heat resistance; double-layered case structure with increased steel outer shell, conic aluminum plug and rubber plug of high temperature fluoric rubber for raised structure sealing and pressure resisting performance; and Ni-Cr wire for ignition for raised antistatic safety performance. The present invention has heat resisting performance up to 230 and pressure resisting performance up to 60MPa for safe detonation in well.
