FIELD: mining engineering. ^ SUBSTANCE: gas-generating composition is intended for oil producing wells activation with the help of overpressurisation and high temperatures. Gas-generating composition for oil producing well activation includes mass.%: epoxy binding agent 12.0 - 22.0, fine aluminium 0.5 - 20.0, hardener - isometyltetrahydroftal anhydride 3.0 - 7.0, oxidant - potassium perchlorate, potassium nitrate is the rest. Producing method of explosives of the stated composition includes mixing of the components and pressurising in formable tooling, made as semocylinders, fastened before filling of stated composition and dismantling after its hardening. ^ EFFECT: increasing of gas volume while combustion; thermal stability and fire-explosive prevention of the composition. ^ 2 cl, 1 tbl |
