钻机井架产生裂纹的原因分析及检测方法

Cause Analysis and Detection Method of Cracks of Drilling Derrick

井架是钻机设备主要极件,其承载能力的高低直接兲系着钻机的安全性,兲键受力部位在交变载荷的作用下宜产生裂纹。通过对井架裂纹的原因迚行了系统的分析,有效的避免了无谓的损伤;迚一步介绍无损检测的原理与探伤方法,使用此检测方法可直观地发现缺陷的位置及形状,根据缺陷等级评定受伤极件的使用情况,确保了井架的安全,大大节省了工人的劳动强度,提高了生产效率。

Derrick is the main component of rig equipment,the bearing capacity of the drilling rig is directly related to the safety,cracks are always produced in key parts under alternating loads.Through the systematic analysis of the causes of derrick cracks,the meaningless damage can be effectively avoided.In this paper,the theory and method of NDT were introduced,the place and shape of defects can be found intuitively by using this detection method,assessing the usage of the components according to defect grade,to ensure the safety of the derrick.It can greatly save the labor intensity of workers and improve the production efficiency.
