| 摘 要： | 塔里木油田钻井条件苛刻,钻杆受力情况复杂,容易发生钻杆失效事故。分析了钻杆失效的原因,介绍了相应的预防措施及其效果。认为现有钻杆标准不能满足塔里木油田的使用要求。多年实践证明,塔里木油田通过制定钻杆订货补充技术条件和严格现场探伤规范,有效地减少了钻杆失效事故,延长了钻杆使用寿命。

| Abstract: | The well-drilling operation conditions in Tarim Oil Field are so harsh that drill pipes are under complicated loads,and thus apt to fail to operation.Failure causes of the said drill pipes are investigated,and relevant preventative actions and their effectiveness are elaborated.It is regarded that the prevailing drill pipe standard can be no longer satisfactory to the application requirements for drill pipes as used in Tarim Oil Field.Years＇ operation practices of the oil field have proven that drill pipe failure rate has been significantly reduced,and drill pipe service life prolonged,due to the supplementary technical terms for ordering,and the stringent site NDT specification as established by Tarim Oil Field. |
