从国产连续油管成功研制看我国焊管产品结构调整

简述了连续油管的发展历史和国产化试制的成功,分析了中国钢管产业的主要特点及全球钢管业的发展趋势,阐述了焊接钢管与无缝钢管油井管在我国的调整趋势,并通过焊接钢管与无缝钢管油井管的性能对比分析,认为HFW油井管各项指标优于无缝管,在油井管领域焊管将逐步取代部分无缝管,并提出焊接钢管与无缝钢管的发展应当统筹规划,制定统一的钢管标准,进而在油井管等领域发挥各自的特长,互补共赢。

Analyzing Structure Adjustment of China Welded Pipe Product from Successful Trial-production of Domestic Coiled Tubing

This article briefly introduced development history and localization successful trial-production of coiled tubing,analyzed main characters of China steel pipe industry and development trend of world steel pipe industry,and expatiated adjustment trend of welded steel pipe and seamless steel pipe,as well as OCTG in China.Through contrastive analysis on properties of welded steel pipe,seamless steel pipe and OCTG,the results showed that each index of OCTG is better than that of seamless steel pipe,and welded pipe will take place of part seamless steel pipe gradually in OCTG field.Finally,it put forward that the development of welded pipe and seamless steel pipe should be overall planned,establish unified standard,and then play its advantages in OCTG pipe field and realize mutual complementary.
