FIELD: oil and gas production.
SUBSTANCE: perforator comprises a hollow body comprising separate sections with jet attachments. For connection of sections a perforator is equipped with spacers of a different length and couplings. The connection is made as a butt joint by means of couplings arranged from outside, and the connection ends of couplings, spacers and each section are arranged with the right and left threads.
EFFECT: higher reliability and durability of sand jet perforator operation, reduction of its dimensions, making it possible to use it in casing strings of a smaller diameter, in casing strings of a larger diameter with a complex profile.
