The invention discloses a high-performance oil casing pipe connecting joint provided with special threads. The modified API buttress threads are machined in a coupling and tube body threaded connecting part. Each inner thread and the corresponding outer thread are tightly connected. The tail end of each buttress inner thread of the coupling is provided with a convex and incomplete V-shaped structure; meanwhile, the tail end of each tube body buttress outer thread is provided with a concave and complete V-shaped structure; and the incomplete V shapes and the complete V shapes form auxiliary seals and auxiliary circular beads correspondingly. A spherical surface seal face and a conical surface seal face arranged at the tail end of each incomplete V-shaped structure of the coupling are in interference fit with a conical surface seal face and a spherical surface seal face arranged at the tail end of the corresponding tube body complete V-shaped structure, so that main seal structures are formed. A groove type inner circular bead formed in the tail portion of each conical seal face of the coupling makes contact with a convex type outer circular bead arranged at the tail end of the spherical surface seal face of the corresponding tube body, so that main circular beads are formed. The high-performance oil casing pipe connecting joint provided with the special threads are good in seal performance, high in safety and reliability, and capable of bearing large bending, high torque, large axial extension and large compression deformation.
