A slewing bearing rotary device, a winch assembly, a remote control device and a multi-way valve explosion-proof box are arranged on the injector head skid. Hydraulic pipelines are arranged on the first blowout preventer skid and the second blowout preventer skid. Connectors are arranged between the injector head skid and the first blowout preventer skid, and between the first blowout preventer skid and the second blowout preventer skid. Leg assemblies are arranged at the four corner ends of the base skid. The tower also includes a transportation tooling.

[0005] As an optimization, the lengths, widths and heights of the injector head skid, the first blowout preventer skid and the second blowout preventer skid are the same, and the lengths are all less than the length of the base skid.
