摘要
介绍了国内高频焊热轧(SEW)油套管的开发情况,SEW工艺的特点,以及采用SEW工艺开发的API油套管、BSG-80T/TT及BSG-110T/TT高抗挤套管、BX55及BX80膨胀套管的技术特征和产品性能,并对SEW油套管的研发方向进行了展望。
Elaborated in the article are the situation of domestic R ＆ D of （SEW） tubing/casing, the characteris- tics of the SEW technology, and the technological characteristics and product propertis of the API tubing/casing, BSG-80T/TT and BSG-110T/TT high collapse resistance casings, and BX55 and BXS0 expandable casings as developed with the SEW technology. Finally, the orientation for R ＆ D of the SEW tubing/casing is prospected.
