The roller stabilizers reamer are used to ream a hole or to stabilize the drill string in the borehole.The reamer body has an upper threaded box and a bottom threaded pin. On the outside part of the body three roller devices

are assembled.The rollers are installed so that they can be dismantled and replaced as required. For borehole reaming operations, special rollers of various shape and hardness are used according to the type of formation

being drilled and reamed.* Roller stabilizers reamer diameter 7 1/2 - 17 1/2 in ( 190,5 - 444,5 mm)* Drill pipe size 3 1/2 IF - 7 5/8 Reg

INTEGRAL BLADE STABILIZERS

Integral blade stabilizers are designed to mantain stiffness of the drill collar string in order toprevent the deflection of the borehole and to ream the drill hole.

According to their position in the drill collar string the integral blade stabilizers are used asfollow:

* Stabilizers for rock-bit - placed just above the bit for borehole reaming.* Stabilizers for the string -placed in the drill collar and drill pipe string, at different distances

from the bit.* Integral blade stabilizers diameter 5 5/8 - 17 1/2 in ( 142,8 - 444,5 mm)* Drill pipe size 3 1/2 IF - 7 5/8 Reg
