The upsetting and thickening of the pipe-end of the drill pipe is a very important process in the production process of the drill pipe. After upsetting at the pipe-end， the wall thickness of pipe body and pipe-end are different， which will cause the mechanical property deviation of pipe body and pipe-end during quench and temper heat treatment. This leads to large differences in the yield strength， impact toughness， hardness and grain size of the material， which is not conducive to the safe operation of high strength and high toughness drill pipe. Tianjin Pipe Corporation has developed secondary Q&T procedure， by 900 ℃for 30 min quenching + 650 ℃ for 60 min tempering + 900 ℃ for 30 min quenching + 650 ℃ for 60 min tempering to fully refine the grain size， improve the strength and toughness， and reduce the uniformity of pipe body and pipe-end .Final the yield strength of both pipe body and pipe-end are 1 140 MPa-1 300 MPa， tensile strength beyond 1 200 MPa. The CVN at -20 ℃ impact energy reached to 100 J for longitudinal pipe body and 80 J for longitudinal upset end at room temperature. The excellent strength and toughness character， and the uniform property of pipe body and upset assures the drill pipe can be used safelyIt provides good material performance guarantee for the safety of ultra-high strength and high toughness drill pipe in the ultra-deep wells which more than 9 000 meters.
