Brigtway can design and produce PDC reamers of different types and sizes. The models and specifications are complete. Used in drilling tool assembly for repairing wellbore walls. Replace the stabilizer to reduce the lateral vibration of the drill bit during the drilling process. Solve the problem of excessive torque during drilling.
When rapidly drilling in formations with good drilling performance, the PDC reamers can timely repair the wellbore wall, smooth the wellbore, and effectively repair irregular wellbore problems such as reduced diameter and keyway. The fully covered toothed structure can effectively remove excess rock debris attached to the wellbore wall. Effectively reduce non production work time. Ensure smooth tripping and wellbore cleanliness. The PDC composite sheet with special shapes makes the contact between the reamer and the wellbore more stable during drilling, reducing the radial vibration of the drilling tool assembly during the drilling process.
● While drilling, straighten and make eye cuts to ensure smooth wellbore rules;
● Dual directional drilling function, effectively handling complex problems such as wellbore shrinkage and collapse;
● Full angle closed reaming design enhances the stability of downhole drilling tools;
● PDC ensures full coverage of the diameter, improving the efficiency of eye scratching;
