摘　　要：采用有限元技术分析了AD24井φ139.7 mm钻杆断裂失效的原因,利用测量统计结果得出双台肩钻杆接头承载能力大幅下降是钻杆接头产生疲劳断裂的主要原因,为采取相关的预防措施提供了理论依据。The φ139.7 mm pipes were used to drill in AD24 well,crack happened on 39 pipes.With a large proportion of rupture,it had inherent reasons.Therefore,finite element technique was adopted to quantitatively analyzing the reasons of the failure,in order to take corresponding prevention measures to provide theoretical basis.Moreover measuring statistical results were used and bearing capacity decreasing of double shoulder pipe joints was the main reason of fatigue fracture.
