摘　　要：采用"高频电阻焊+热张力减径+全管热处理+高温矫直"工艺开发了BSG-110TT高抗挤套管,对比分析了不同工艺阶段套管的组织及性能变化规律;对开发的高抗挤套管进行了机械性能测试,并与无缝高抗挤套管进行了对比。结果表明,BSG-110TT高抗挤套管在几何尺寸精度、残余应力、抗外压挤毁性能方面具有较大的优势,且采用上述工艺,较好地解决了焊缝冲击韧性低及抗腐蚀性能差的问题。＂High frequency welding,hot stretch reducing,full body heat treatment and high temperature straightening＂process was adopted to produce BSG-110 TT high collapse resistance oil casing.The evolution of microstructure and property of casing steel at different process stage was analyzed.The mechanical properties and corrosion resistance properties of BSG-110 TT were also tested.The results show that the dimensional accuracy,residual stress and collapse resistance of BSG-110 TT are much better than high collapse resistance seamless oil casing tube.Moreover,the used production process benefits to solve the problems of low impact toughness and poor corrosion resistance of weld zone.
