Great - Model BHA -PDC Reamer

A new pattern to prevent & solve the down hole complication situation. Supply a safety & efficiency drilling environment.  Reduce a large mount of NPT(non production time). Absolute guarantee for smooth tripping and clean borehole. Fast drilling in the soft formation,limited by the length of the bit gauge,the bore hole trajectory is irregular,this situation caused bit bouncing, high torque and drag . The Crocodile Reamer can trim the irregular well side by scraping the tight,key- seating.etc sections to make the side smooth. The “full coverage”cutters roundly cutting the  needless rocks. Special shaped cutters on the reamer supply series  supporting point on the contact between the BHA and  hole wall,it can reduce the radial vibration.
