FIELD: chemistry.
SUBSTANCE: invention relates to compositions which can be used in making shaped charges for the oil industry. Heat-resistant shaped charge used in oil and gas wells contains an explosive substance of Okfol 3.5. When making the shaped charge, activated carbon powder is introduced into it as a sorbent, with the following ratio of components, wt.%: Okfol 3.5 95–99.5, activated carbon powder 0.5–5.
EFFECT: higher heat resistance of shaped charge to 200 °C and increasing its penetration capacity.
