The PKO 73-AT perforators are one of the modifications of perforating systems for drilling and blasting operations in wells. The devices are used in combination with shaped charges and are mainly used for secondary opening of oil-bearing formations in liquid-filled cavities. Suitable for casing columns with a diameter of 114 mm.
The parameters, characteristics and dimensions of the PKO 73 are specified in detail in the accompanying technical documentation attached to the modification of the perforation systems.
