Shaped charge perforators and its applications tocreate holes in rocks and soils

摘要

Shaped charge belongs to a directional energy device in explosion devices, and it isrnwidely used in mining and petroleum extraction. However, the existing shaped charge rock perfo-rnrators have disadvantages such as large weight, bad hole shape, broken orifice and shallow depth.rnThese disadvantages greatly constrain the applications of rock perforators. The shaped chargernperforators developed by us, which solved the above-mentioned disadvantages, are portable andrneasy to use.
