| 摘 要： | 用旋转弯曲腐蚀疲劳试验评价了４５钢在聚合物钻井液中的腐蚀疲劳敏感性，对应力，Ｃｌ－，ｐＨ值以及缓蚀剂的影响进行了研究，并用断口形貌照片进行证实．结果表明４５钢在聚合物钻井液中具有腐蚀疲劳敏感性，并随介质腐蚀性加强而加剧，添加缓蚀剂则能降低其敏感性

| Abstract: | The corrosion fatigue of carbon steel in drilling fluids has been studied out with a self made rotary type of bending corrosion fatigue testing apparatus under simulated drilling conditions. The effects of stress, Cl -, and the value of pH and the inhibiting action of the imidazoline inhibitor on corrosion fatigue are studied. The experimental results show that the susceptibility of carbon steel to corrosion fatigue in drilling fluid is increased when the corrosion is accelerated. |
