摘要:
连续管强度级别的提高有利有弊。一方面由于其拉伸载荷极限、抗扭极限、爆破极限以及挤裂极限的增加，使得连续管可以在更高压力、更大长度范围内应用；另一方面，随着强度级别的提高，其塑性、韧性降低，并且对环境裂纹的敏感性也在增强。初步试验结果表明，对于屈服强度分别为690MPa（100ksi）和758MPa（110ksi）的新一代高强度连续管，其商业可适用的最小屈服强度级别为620MPa（90ksi）。
Abstract:
An overview of higher strength coiled tubing is presented with the advantages and disadvantages associated with the higher strength grades.The advantages include increased tensile load，torsion，burst and collapse limits.These increased limits permit coiled tubing to be used to higher pressures，longer lengths and increased applications.The disadvantages include decreased ductility and toughness with increased susceptibility to environmental cracking.Knowledge of these advantages and limitations permit safe use of these higher strength grades of coiled tubing.Data is presented on a commercially available 90 ksi minimum yield strength grade with initial test results of a new generation 100 ksi and 110 ksi yield strength grades.
