The utility model relates to a multistage pulse increase perforator of interior orientation, the advantage that firing angle perforator and multistage pulse increase perforator are decided in the interception has been synthesized to this perforator, it is that the firing angle perforation is decided in an album interception to be it, the gaseous fracturing of integral type increase perforation and multistage pulse high energy is novel perforation technique all over the body, the utility model discloses a can be with the perforating bullet towards direction perforation that the permeability is best when not only having fused the perforation in the inclined shaft interception perforation technique, thereby make the advantage of the productivity fold increase of oil gas well, and simultaneously, the gaseous energy to fracture reinforce of high energy in the gaseous fracturing technique of multistage pulse high energy has been fused again, the width generation capacity good with can prevent the advantage of stratum crack -closure, has fine increase effect.
