摘　　要：分析了西部油田多年钻杆大量疲劳刺漏的原因,认为127 mm钻杆不适合深井、超深井的的大拉力、高扭矩、高转速、大狗腿、强腐蚀等等复杂工况。通过计算论证,表明只有大直径钻杆才能满足深井、超深井安全钻进的要求,提出了用于深井的大直径钻柱设计思想,推荐了可用于深井、超深井的大直径钻杆。This paper analyse the causes of drillpipe fatigue leak at a west oilfield in many years, it is realized that 127 mm drillpipe do not suit the great pull force, great torsional moment, rapid rotate speed, big dogleg, strong corrosion, etc. ,conditions in deep and extra deep well. Through computation and analysis, it is show that large diameter drillpiepe can meet the demand for drilling deep well safety. The idea of large diameter drillstring design is put forword and large diameter drillpipe is recommended for deep well.
