Quadruple-operation testing tubular column suitable for ultra-deep well oil and gas well and using method of quadruple-operation testing tubular column

The invention discloses a quadruple-operation testing tubular column suitable for an ultra-deep well oil and gas well and a using method thereof.The tubular column comprises a well logging tool, a packer and a perforation assembly which are sequentially arranged from top to bottom and further comprises a back-insertion sealing connector and a screen pipe, and the back-insertion sealing connector is arranged between the tool and the packer; the screen pipe is arranged between the packer and the perforation assembly; and the packer is a permanent packer. The permanent packer is used, so that the setting and sealing reliability of the packer is greatly improved, and the blowby risk during construction is reduced; a process of perforating first and then setting the packer is adopted, so that the influence of detonation effect is eliminated, and the risks of sealing failure of the packer and breakage of a tubular column caused by detonation are avoided; underground accidents caused by the fact that a packer cannot
