HEAT-RESISTANT ENERGY-SATURATED COMPOSITION FOR PERFORATORS CUMULATIVE CHARGES Russian patent published in 2019 - IPC C06B25/34 C06B25/04 E21B43/117 E21B43/248

Abstract RU 2699134 C1

FIELD: blasting operations.

SUBSTANCE: invention relates to a heat-resistant explosive composition used for blasting operations, making perforation systems and repairing in deep oil wells under conditions of high temperatures and pressures. Heat-resistant explosive composition contains the following components, wt%: pyridine 93.5–98.5, organofluorine rubber 1–5, oxysin 0.5–1.5.

EFFECT: invention is aimed at increasing the threshold of thermal stability of explosive composition by using a heat-resistant explosive, which is safe to handle and can be used in deep wells with temperature of up to 300 °C.
