VGM73 hydro-mechanical firing head is an iniang device for TCP Scorpion and KPO perforang guns used in oil, gas and other wells.
It is used for operaons in vercal, direconal and horizontal wells.
In horizontal and direconal wells (with inclinaon angle more than 45 degree) VGM73 is iniated by a rubber ball dropped into the tubing cavity and pushed through under pressure. In vercal and direconal wells (with inclinaon angle less than 45 degree) VGM73 is iniated by a drop bar.
Specific Features
- Easy and reliable assembly;
- Safe operaon: required hydrostac pressure for iniaon of the firing head is not less than 5 MPa
- Flexibility: can be used in wells of all types – vercal, direconal and horizontal;
- Not used in highly absorbing wells where hydrostac pressure can be less than minimum.
