FIELD: imploding works; technological processes.
SUBSTANCE: invention relates to methods for manufacturing shaped charges for perforating systems used to enhance oil recovery. Method for increasing the temperature resistance of explosives containing the main explosive, phlegmatized with technical paraffin, in which the main explosive is in the form of crystals coated with a technical paraffin, is encapsulated with a second explosive, and the space between the encapsulated crystals is subsequently filled with a second explosive. As the second explosive hexogen or octogen is used. As the second explosive, phlegmatized explosives are used.
EFFECT: invention makes it possible to increase the thermal stability of the shaped charges and the reliability of their operation.
