Abstract: The present invention provides a method for manufacturing a superior 13Cr friction-welded drillrod, the method comprising the following steps: manufacturing a superior 13Cr tube body; manufacturing a superior 13Cr internally threaded coupler and a superior 13Cr externally threaded coupler, respectively; connecting the superior 13Cr internally threaded coupler and the superior 13Cr externally threaded coupler respectively to the two ends of the superior 13Cr tube body by means of frictional butt welding; after heating seam areas to 950° C.-1000° C., cooling same to below 200° C. by ejecting compressed air onto the surfaces of the seam areas, and then cooling the seam areas to room temperature by spraying water; and tempering the seam areas by heating same to 640° C.-700° C. By the present method, a superior 13Cr friction-welded drillrod can be manufactured, which, in the case of the exploration of a gas filed containing a relatively high level of CO2, can be not only used as a drillrod in an earlier stage of nitrogen well-drilling operation, but also used as an oil tube in a later stage of well completion with oil tube.
