The new diamond drill rod adopts an integrated threaded connection design, eliminating stress concentration points of traditional threads, reducing leakage and fracture risks, increasing fatigue life cycle by 38%, and significantly lowering the probability of fatigue fractures.
By optimizing the cross-sectional shape to distribute stress, the lifespan under cyclic loading is improved, further enhancing the adaptability of drill pipes in complex formations.
For different formation characteristics (such as high temperature, high pressure, and high corrosion), new drill pipes can optimize material and structural parameters to enhance adaptability. For instance, high-toughness drill pipes meet the requirements of low-temperature, acidic environments, and ultra-short-radius radial horizontal drilling by refining pure steel (S≤0.010%, P≤0.015%) and adding alloy elements like Cr and Mn.
