Plastic Deformation of Metal Continuous Capillary Tubes for Logging Analyzed by Using ABAQUS Software


摘要(Abstract):

针对金属连续毛细管因在测井绞车滚筒上的弯曲行为而产生塑性变形对性能的影响,采用有限元软件ABAQUS分析不同弯曲半径时金属连续毛细管产生的塑性变形和疲劳寿命。结果表明:金属连续毛细管在弯曲过程中的塑性变形随着中性层向外逐渐增大;当弯曲半径由75 mm增加至150 mm时,随着弯曲半径的增加,金属连续毛细管的塑性变形逐渐增大,等效塑性应变由3.5×10~(-2)减小至1.46×10~(-2),并且使用寿命逐渐趋于平缓,循环次数由25 000增加到398 107。
