The steel grade of drill pipe refers to the grade of drill pipe steel, which is determined by the yield strength of the drill pipe steel. The API (American Petroleum Institute) divides drill pipe steel grades into five levels: D, E, 95 (X), 105 (G), 135 (S). The higher the steel grade of the drill pipe, the greater the yield strength of the pipe, and the greater the various strengths of the drill pipe. In the strength design of drill string, it is recommended to use the method of increasing steel grade to improve the strength of drill string, rather than increasing wall thickness.
(1) Apply drilling pressure to the drill bit;
(2) Ensure necessary strength under compression conditions;
(3) Reduce the vibration, swinging, and jumping of the drill bit to ensure smooth operation of the drill bit;
(4) Control well inclination.
