Perforating tubular column and method for depth correction and perforation

Embodiments of the invention provide a perforating tubular column and a method for depth correction and perforation. The perforating tubular column comprises a perforating gun, a pressure perforating detonation device, and two depth correcting short sections. Through the two depth correcting short sections of the perforating tubular column respectively performing depth correction operation, a depth correction chance is added, so as to reduce the number of lifting and lowering the perforating tubular column, and improve depth correction and perforation job efficiency. 本发明实施例提供种射孔管柱和射孔管柱校深及射孔方法。本发明射孔管柱，包括：射孔枪和压力开孔起爆装置和两个校深短节；本发明实施例通过射孔管柱设有两个校深短节分别进行校深作业，增加了次校深机会，从而减少了射孔管柱起下的次数，提高校深及射孔作业效率。
