Hilong Slim Drill Pipe

Product Introduction 

The Hilong slim drill pipe is a non-standard drill pipe developed by Hilong in combination with pipe-end internal upsetting forming technology and high-performance premium connection. It can provide effective solution for small-hole drilling, short-radius horizontal well drilling, oil well workover and secondary exploitation.

Product Advantage

The tool joint outer diameter of Hilong slim drill pipe is close or equal to the outer diameter of the drill pipe body. It has the characteristics of small tool joint outer diameter and good drill pipe flexibility. It can be used in slim hole where conventional drill pipes cannot be used, and it is suitable for workover, window sidetracking and other operations.

The smooth outer wall of the drill pipe reduces the risk of sticking and the difficulty of releasing the pipe. Compared with the conventional drill pipe, it is more suitable for horizontal drilling.
Under the condition of the same borehole size, the reduced outer diameter of the tool joint increases the clearance between the drill string and the borehole wall, which makes the curvature of the kick off point larger, and can realize short radius and ultra-short radius drilling
