摘要
Abstract
In response to the issue of insufficient tensile strength of the drill pipe as used for deep earth oil-gas ex-ploitation in the country,relevant critical technical bottlenecks have been overcome,including upsetting of the extra heavy pipe body,heat treatment,and friction welding,etc.,resulting in the R&D of the Φ168.3 mm drill pipe as used for the extra-deep well.The result shows that the said drill pipe possesses such properties as maximum suspended load up to 942 t,and weld maximum suspended load up to 1 041 t;the pipe body transitional section is long over 140 mm,which properly distributes the pipe-end stress,and enhances the efficiency and safety of drilling the said well.The R&D has promoted the successful completion of the 10 910 m drilling operation of the Well Shenditake 1,supporting the develop-ment of the domestic deep earth engineering.关键词
