description The utility model relates to a three-jet-flow gathering perforation device and mainly solves the problem that conventional perforators existing in prior art limit perforation depth and perforation diameters and compaction bands formed by perforation passages can not be crushed. The three-jet-flow gathering perforation device is characterized in that every three perforating bullets of a perforating bullet A (13), a perforating bullet B (14) and a perforating bullet C (15) form a group, each group of the perforating bullets is loaded in a perforating bullet support (8), the perforating bullet A (13), the perforating bullet B (14), and the perforating bullet C (15) correspond to a blind hole A (4), a blind hole B (5), and a blind hole C (6) on a perforation gun body (1) respectively, and in each group of the three perforating bullets, two nonadjacent perforating bullets form a certain angle a with a perforating bullet carrier (7). The three-jet-flow gathering perforation device can crush the compaction bands for
