加强应用电磁探伤,提高钻具使用质量加强应用电磁探伤,提高钻具使用质量 摘要:随着钻井技术的不断进展,为提高机械钻速,井下动力钻具的使用增多,钻柱转速提高,对钻具质量的要求也越来越高
钻具在钻井过程中承受轴向力、弯矩、离心力、扭转力以及动载的作用,工况条件极其恶劣
特别是深井、斜井、水平井,钻具中微小的缺陷就可能导致井下钻具事故

Drill in drilling process to bear the axial force, bending moment, torsion force and the centrifugal force, dynamic loading, the condition is extremely bad
Especially in deep well, inclined shaft, horizontal well, drilling tool in tiny defect may lead to a downhole drilling tool accident
