The following terms and definitions apply to this standard
Perforation construction qualification rate The percentage of qualified non-perforating construction in the total number of perforating constructions evaluated by rate is calculated by formula (1):
L:C/S×100%
Wherein:
L-perforation distance T qualified rate:
the number of qualified perforating constructions in the batch;
the total number of perforating constructions in the reported period.
The perforating charge firing rate perforating chargesbotrate refers to the percentage of the number of perforating charges actually fired to the number of perforating charges installed. The calculation method is shown in formula (2):
D = A/H × 100%
In the formula:
—fired perforating charge;
A——the number of perforating charges actually fired when going downhole;
Number of perforating charges installed.
