The utility model relates to a multistage shaping device of impacted style belongs to the oil gas field and is out of shape tube shaping in the pit and repairs and to use instrument technical field. Comprise body, expand tube section and direction head, body outside of tubes middle part is equipped with tertiary expand tube section, and body and expand tube section adopt integral type structural design, and the body lower part is the direction head. Multistage shaping device of impacted style to tertiary expand tube section is the example, and from the bottom up expand tube section external diameter increases in proper order step by step, once runs the drilling tool into the well to make the expansion of deformation cover internal diameter of pipe reach cubic plastic construction effect, has improved plastic efficiency, be equipped with plastic section, guarantor footpath section and lower plastic section three in every grade of expand tube section, the in -process is transferred to the drilling tool, and the internal diameter of pipe is overlapped with deformation sleeve pipe contact, crowded bloated the deformation to lower plastic section, and lifts the in -process, goes up the plastic section to work, realizes two -way plastic, and in addition the guarantor of sizing section directly acts on, can obviously improve the plastic effect, adopt integral type structural design, install overall intensity height.
