Abstract

Устройство для перфорации подземного пласта может содержать обсадную трубу, энергетический материал, вкладыш и кислотообразующий материал. Колонна может иметь конец с щелевым отверстием, выполненный с возможностью приема детонационного шнура, и открытый конец. Энергетический материал может быть размещен на открытом конце и в баллистическом. Вкладыш может вмещать открытый конец и может содержать кислотообразующий материал, который выполнен с возможностью образования кислоты при детонации взрывчатого материала.
