FIELD: chemistry.
SUBSTANCE: invention relates to compositions which can be used in making shaped charges of perforators for the oil industry. Heat-resistant shaped charge used in oil and gas wells contains an explosive substance of Okfol 3.5. When making a shaped charge, activated carbon powder and an additive in the form of potassium perchlorate are added to it as a sorbent, with the following ratio of components, wt.%: Okfol 3.5 80–99, activated carbon powder 0.5–5, potassium perchlorate 0.5–15.
EFFECT: higher heat resistance of shaped charge to 200 °C and increased penetration of steel or concrete targets.
