Beneficial effect
Firing angle perforating system is determined in the measurable interior orientation orientation in a kind of orientation proposed by the present invention, the bullet in perforating system
Frame is that firing angle firing mount determine in the rotation of integral type counterweight, using the mechanism of upper righting pipe 7 and the uniqueness of lower righting pipe 8 by the firing mount in rifle string
An entirety is connected as, in the case where hole angle is more than 20 °, gravity self orientation principle can be relied on to make firing mount string overall simultaneously
Rotate orientation, then using determine firing angle the characteristics of, enable perforation ejection stream when pit shaft is with oil-gas Layer oblique it is parallel with it is oily
Gas-bearing formation perforation.Determine firing angle perforating system with existing interior orientation inclined shaft orientation to compare, it solves after rifle string is gone into the well and is merely able to survey
The orientation of lower first perforating gun carrier of initiator is tried, and the weak point in firing mount orientation in whole rifle string can not be tested, is ensured
The accuracy and precision in whole tubing string test orientation.More reliable, more accurately perforating technology is provided for oil mining, can be had
Effect improves such a well capacity.
