Description

 

Back-Reaming Stabilizers is selecting the appropriate location and through special proccessing 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 a well, making trajectory of borehole as far as possible to achieve ideal condition and preventing the phenomenon of Dogleg. Especially in a drilling process, more often than not leading to drilling difficultly 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 asving time and costs for drilling.
