The dimensional accuracy,residual stress and collapsing resistance of HFW casing,SEW casing and seamless casing were studied in this paper.The results show that compared with seamless casing,HFW and SEW casings are much better in the aforementioned characteristics.Moreover,employment of SEW process can properly solve the problems of low impact toughness and poor corrosion resistance at welded joints.Therefore,using SEW casing can avoid low collapsing resistance of seamless casing when other factors are fixed,and thus can completely meet the requirements of oilfield customers.
