Detonation system for detonating explosive charges in well |
摘要 |
In well perforating operations, it is necessary to detonate shaped charges suspended in the well. To avoid dangerous detonation at the surface, a pressure responsive mechanism is set to respond to a pressure indicative of operation at a selected depth. This pressure setting arms the detonator in cooperation with an electrical arming mechanism operative in response to a selected current flow at a required voltage for a selected interval.
