摘要
采用高频电阻焊、热张力减径及全管体热处理工艺开发了J55、N80Q、P110、BSG-80TT、BSG-110TT及BX55钢级SEW石油套管,对开发的SEW套管进行了尺寸、力学性能等检测。结果表明:与同钢级无缝管相比,SEW石油套管管体的强韧性匹配好(冲击韧性提高了约30%)、几何精度高、壁厚公差小,在相同井深下可减少钢管用量约3%;BSG-80TT/110TT高抗挤套管的抗外压挤毁性能高于Q/SY 1394—2011标准要求值8%以上;BX55钢级SEW膨胀套管在塔河油田成功完成深井侧钻水平井膨胀套管完井作业,创当时膨胀管下入井深最深、井斜最大、连续膨胀距离最长3项国内纪录。
Oil casings of the SEW series,such as J55,N80 Q,P110,BSG-80 TT,BSG-110 TT and BX55 expandable casing,aredeveloped by means of the processes like HFW,heat stretch-reducing and pipe over-length heat treatment.The developed casings of theSEW series are tested for sizes and mechanical properties.The results indicate that the SEW oil casings have a better performance forstrength and toughness than seamless casing of the same steel grade.The impact tenacity of the SEW casing is improved by about 30 percent.The consumption of steel pipe is reduced by about 3 percent at the same well depth owing to high geometric precision and smallwall thickness tolerance of the SEW casing.Collapse resistant strength of BSG-80 TT/110 TT is 8 percent higher than the required value ofQ/SY 1394-2011.The SEW expandable casing of BX55 steel grade is successfully used in expandable casing completion service for deepsidetrack horizontal well in Tahe Oilfield,making three domestic records for expandable casing at that time-the deepest well for tripping-in,the largest deviation angle and the longest distance of continuous expansion.
