Special Stabilizer With Reamer And Back-reamer

Special stabilizer with reamer and back-reamer is an important tool in the drilling process to control the well deviation. It can increase the bit service life, drilling speed and well quality by effective stabilization. There are several cutting teeth special fixed on upper end and lower end of crown for reaming and back reaming. In the process of drilling and tripping, it can play the role of two-way cutting, repair the well wall, make the well trajectory to reach the ideal condition as far as possible, and prevent the phenomenon of doglegs. Especially in tripping process, it always hard to trip because of hole shrinkage, etc. At this time, the back reaming teeth can play a cutting role to eliminate hole shrinkage phenomenon, thus saving time and costs for drilling.
