Dual-direction Pressure Actuated FiringHead
TCP Tools - Firing Head
Dual-direction pressure actuated firing head is used in TCP operation. It is installed between gun strings and
activated by annulus pressurizing.With dual-direction initiation, it highly improves the reliability of detonation
transmission.
Features of the TCP Firing head
●Simultaneous initiation in dual-direction improves the reliabilityof detonation
transmission.
●Simple structure and convenient operation.
● Can be used in the perforation of heavy-oil well, large inclined well,
horizontal well and multi-formations perforation.
