Drill pipes may fail at any part during the drilling process, leading to serious consequences or even scrapping. According to statistics, about five to six hundred drill pipe accidents occur in various oil fields in China every year, causing huge economic losses. With the depletion of shallow resources, the drilling of deep and ultra-deep wells has become more common, and the safety and reliability of drill pipes is particularly prominent. Drill pipe failure is generally manifested as body fracture and puncture, failure of drill pipe threads, etc. The reasons are generally caused by the following factors: basic mechanical working conditions of drill pipes during drilling, combination of drilling tools and drilling technology, regularity of parallel diameters, eccentric wear, thread sealing grease, drilling fluid, drill pipe structure and materials, formation factors, and internal corrosive media, etc. The interaction of the above factors leads to drill pipe failure.
