Visual high-power well opener with tubular column structure

The utility model relates to a tubular column structure visualized high-power well opener, which comprises a pressure-bearing shell, a magnetic positioning sensor is sleeved in the pressure-bearing shell, and when the well opener enters a well and is put down, the magnetic positioning sensor passes through a tubing coupling, a packer and a concentric water distributor in a water injection tubular column, and the magnetic positioning sensor is positioned in the pressure-bearing shell. Different magnetic positioning signals are represented according to changes of ferromagnetic media of the tubing coupling, the packer and the concentric water distributor, and the magnetic positioning signals are collected through a magnetic positioning signal collector arranged on the ground to form a magnetic positioning signal curve. And determining the depth positions of a tubing coupling, a packer and a water distributor in the water injection string according to the magnetic positioning signal curve. According to the utilit
