Description

Dustproof guiding die and rotary shaping mechanism matched with same Technical Field The invention relates to the technical field of petroleum exploitation equipment manufacturing, in particular to a dustproof guide die and a rotary shaping mechanism matched with the dustproof guide die. Background Perforation technology is a key link of completion and production increase of oil and gas wells. The collector used in the method generally comprises an annular metal shell and explosive powder (such as explosive powder) filled in the shell. After the perforating bullet is detonated at a preset position in the pit, the generated high-energy metal jet can puncture a casing pipe of the pit shaft, a solid well cement ring and penetrate into stratum rock to form a fluid channel for communicating an oil and gas reservoir with the pit shaft, so that efficient exploitation of oil and gas is realized. To meet the needs of mass production, semi-automated production lines have been commonly used for assembly of the efficiency-increasing device.
