The invention relates to the technical field of oil field downhole operation, in particular to a cased well completion horizontal well shaft reconstruction secondary well completion method and a well completion process pipe column. Pressing and detecting whether the tripped shaft reconstruction process pipe column is intact or not; after it is detected that the tripped shaft reconstruction process pipe column is intact, an annular space between the original casing pipe and the shaft reconstruction process pipe column is filled with a high-strength metal binding agent, and the outer wall of the original casing pipe and the outer wall of the shaft reconstruction process pipe column are mutually bonded; the tripped shaft reconstruction process pipe column is suspended and sealed; secondary well completion of wellbore reconstruction in the cased well completion horizontal well is achieved, and a new wellbore environment is reconstructed; bridge shooting combined operation is adopted in the later period, large-dis
