The stabilizer with backreaming is selecting the appropriate location and through special processing method to array few teeth as a cutting edge. In this way, this stabilizer can be played cutting when the process of drilling and pull out. During drilling process, forward and backward redressing can be played the role to repair and maintain the wall of well, making trajectory of borehole as far as possible, more often than not leading to drilling difficulty because of hole shrinkage, and so on, at the moment, the forward and backward redressing of this stabilizer can be played cutting, to eliminate hole shrinkage phenomenon, thus saving time and costs for drilling.
We can provide all types of stabilizers, in both alloy steel and non-magnet materials:
1. Spiral integral blade stabilizer
2. Straight integral blade stabilizer
3. Non-magnet integral blade stabilizer
