Abstract


The article discusses the practical effectiveness of support-centering elements in constructing directional wells, focusing on the advantages of a roller reamer that reduces torque in the lower part of the drill string due to its decreased contact area with the rock formation. This enhances drilling quality and borehole shaping, ensuring stable operation and reducing load on the wellhead, making the reaming a promising tool for modern drilling technologies.

Key words:

oil, gas, drilling, stabilizer, roller stabilizer, roller reamer
