The invention relates to the technical field of shaping repair of damaged casing pipes, in particular to a hydraulic shaping pipe column and a casing pipe shaping process. The hydraulic shaping pipe column comprises an oil pipe, a shaper and a hydraulic booster, wherein the hydraulic booster comprises a two-way booster and a hydraulic commutator; the two-way booster comprises a piston cylinder anda piston; the piston and the piston cylinder are matched to form a shaping chamber and a lifting chamber; the hydraulic commutator comprises a commutator main body; a center hole of the commutator main body is internally provided with a pressure sensing line in a sliding seal and upward anti-slip manner; the pressure sensing line is provided with a liquid feeding channel; the commutator main bodyis internally provided with a shaping channel and a lifting channel; the pressure sensing line has an upper limit and a lower limit in the stroke of up-down reciprocating motion along with the oil pipe; at the lower limit, an inlet of the shaping channel is communicated with an outlet of the liquid feeding channel; an inlet of the lifting channel is communicated with a pressure relief channel; and at the upper limit, the inlet of the shaping channel is communicated with the pressure relief channel, and the inlet of the lifting channel is communicated with an outlet of the liquid feeding channel.
