Universal initiating head (GIU)
Назначение:
Purpose
The SIU activates cumulative perforators lowered onto tubing in wells filled with water, oil or other flushing liquid. The head works with perforators PKO63-AT, PKO73-AT, PKO89-AT, PKO102-AT, PKO114-AT, the explosive chain of which begins with a shock detonator UD BVT or a device similar in susceptibility to detonation. The head is operated mechanically (hydraulically).
