Feature :
Fast drilling in a soft formation with a bit gauge that is limited in length results in an uneven bore hole trajectory, which causes bit bouncing, high torque, and drag.
By scraping the narrow, key-seating, etc. portions, the crocodile reamer may smooth out the uneven well side.
The "full coverage"cutters cutting the unnecessary rocks in a rounded manner
The radial vibration can be decreased by using specially shaped cutters on the reamer supply series supporting point on the contact between the BHA and hole wall.
Notable features :
We provide three PDC reamer kinds in various sizes:
