Oil conduit conveying type gun perforation explosion-proof gun protection method

The invention relates to a tubing conveyed perforation anti-explosion gun protecting method. The method comprises the steps: in the oil gas water well tubing conveyed perforation operation process, a perforating gun is provided with a pressure releasing device consisting of a pressure releasing joint and a pressure releasing gun breech; and when the pressure in the perforating gun is increased suddenly, the pressure in the gun body is released fast by the pressure releasing device so that the pressure inside and outside the gun body is in a balanced state, thus rooting out gun explosion accidents and ensuring the normal running of perforation operation. The method is novel in design and easy to be implanted, has good effect, can be applied in all types of cased wells and is suitable for perforators of various specifications; and by utilizing the method, serious accidents of perforator explosion and the like can be effectively avoided in oil gas water well perforation operation process, the safety is guarantee
