The drill collar is made of aisi4145hm or AISI4145H chromium molybdenum alloy steel rolled or forged materials. Aisi4145hm material is improved on the basis of AISI4145H material, adding CR, Mo and other chemical components, effectively improving the comprehensive mechanical properties of the drill collar and prolonging its service life.

 

Due to the heavy weight and high rigidity of the drill collar, its main functions are:

 

1) Apply WOB to the bit;

 

(2) Ensure the necessary strength under compression;

 

(3) Reduce the vibration, swing, and jump of the drill bit to make the drill work smoothly;

 

(4) Deviation control
