Abstract: The current situations both at home and abroad concerning technologies of OCTG and the development trends are systematically analyzed in terms of the position and role of OCTG in petroleum industry. It is concluded that there is still some gap between China and the developed countries in the field of high-end OCTG technology. It is appealed that the industrial circles should speed up the production localization of hi-grade OCTG, and turn China from a big OCTG producer into a powerful OCTG giant.
