Document Type and Number:
WIPO Patent Application WO/1991/006742
Kind Code:
A1
Abstract:
A method for thermogasodynamic drilling provides for transformation of slow burning of a fuel mixture into detonation with subsequent generation of at least two separate detonation waves moving towards the bottom of the hole in two parallel flows and directed at the bottom at an angle to each other. The device comprises an arrangement (10) for preparation of the fuel mixture, a chamber (1) for ignition of the fuel mixture, an ignition system (2) and at least two pipes (4, 5) connected to the ignition chamber (1) and oriented so that their open ends are directed towards the bottom of the hole and the detonation waves (3', 3'') generated in the pipes are directed to the bottom zone (6) at an angle to each other.
