AI Technical Summary
Technical Problem
Existing glass cutting techniques often leave residue after glass is cut, causing surface damage and affecting product quality.
Method used
A fracturing perforation gun for oil and gas wells was designed. By setting a sealing plate and an elastic device in the projectile hole, and utilizing the cooperation of a support rod and a threaded rod, reliable installation and sealing of the projectile can be achieved, preventing the random movement of residue.
Benefits of technology
It effectively avoids the obstruction of the gun body movement by projectile residue, improves the ease of installation and safety of use of the perforated bullet, and reduces the damage of glass residue to the glass surface.

Abstract
The application relates to a fracturing perforating gun for oil and gas wells, and relates to the technical field of perforating guns, which comprises a gun body, an initiator fixedly installed at the tail end of the gun body, and a plurality of bullet holders fixedly installed in the gun body, a bullet hole fixedly installed in the bullet holder, and a bullet groove formed in the bullet hole; first, the sealing plate is moved to expose the bullet groove of the bullet hole, then the perforating bullet is placed in the bullet groove, at this time, the front end of the first supporting rod abuts against the side wall of the perforating bullet, the two sealing plates are moved in opposite directions to be opened and exposed by cooperation of the first supporting rod and the connecting slide plate, after the initiator, the detonating cord, the detonating guide rod and the detonating guide sheet complete the detonation work, the elastic device pushes the two sealing plates to be close to each other to be folded, the bullet hole is sealed, the bullet residue is prevented from moving at will, the movement of the gun body is hindered, and the gun body is conveniently taken out.
