FIELD: mining.
SUBSTANCE: invention is related to devices intended for perforating oil and gas wells equipped with casing pipes. A needle drill for an oil and gas well perforator is claimed, containing a flexible shaft with an element for connecting to the drive and a tip with a cutting part. The tip is equipped with a holder for fastening and forming the cutting part in the form of a package of wire pile, which is a continuation of the flexible shaft, forming at least one flat cutting edge. At the same time, carbide elements are soldered to the ends of the wire pile.
EFFECT: enabling the ability to regulate the diameter of perforation in the rock filtration zone by increasing the angle of inclination of cutting edges of the wire pile under the action of centrifugal forces.
