针对油田中的钻杆在恶劣工况下形成的横向缺陷,在分析了钻杆管端加厚带探伤难点后,提出了水浸超声检测方法。结合实际情况及其具体要求,设计系统总体探伤方案,并研制出相应探伤系统,制定了自动探伤流程图。结果表明,该系统能为钻杆修复工作提供一个定性定量的可靠依据。 Aiming at the transverse defects formed in the oil field under the harsh working conditions, the water immersion ultrasonic testing method is put forward after analyzing the difficult testing of the pipe end thickening zone. According to the actual situation and its specific requirements, we designed the overall flaw detection scheme of the system, developed the corresponding flaw detection system, and established the flow chart of automatic flaw detection. The results show that the system can provide a qualitative and quantitative reliable basis for the drill pipe repair work.
