Introduction：

The three-roller hole opener is a drilling tool used while drilling, providing functions of stabilization and minor hole opening. It is divided into two types: drill string type and bottom hole type. The tool's rollers are classified into three types: welded tooth type (H1), inserted tooth type (H2), and wide tooth type (H3), designed for abrasive formations, hard formations, and soft formations respectively. It features strong adaptability and a long service life.

Features and Benefits：

★ Converts downhole pressure differential to weight-on-bit, solving directional and horizontal well pressurization challenges.

★ It improves the load distribution on the drilling tool, reduces fatigue damage,and extends the service life.

★ It enhances effective Weight on Bit (WOB), significantly improving the Rate of Penetration (ROP).
