EXPLOSIVE COMPOSITION FOR MAKING CHARGES OF CUMULATIVE PERFORATORS (EMBODIMENTS) Russian patent published in 2020 - IPC E21B43/116

Abstract RU 2734192 C1

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: group of inventions relates to compositions which can be used in making charges of cumulative perforators for oil industry. Explosive composition for making charges of cumulative perforators contains hexogene phlegmatised (hexofol) and fine-grained silicium dioxide or finely dispersed technical silica as a powdered sedimenting agent. In addition, the explosive composition can contain a blasting explosive.

EFFECT: higher threshold of thermal stability of explosive composition.
