Downhole Motors PDM

​

Downhole motors for directional drilling are key tools in the well drilling industry, especially in complex geological formations. Their operation is based on the conversion of hydraulic energy, provided by the drilling fluid, into mechanical energy that generates rotation to advance the drilling process.

Working Principle

The downhole motor uses drilling flow to activate a stator and rotor assembly. As the fluid passes through the cavity between these components, a rotation of the rotor is generated. This movement converts hydraulic pressure into torque that is transferred to the drilling assembly, allowing directional drilling to advance with precision.

Optimization and Advanced Technologies

Modern solutions integrate advanced technologies in the power and transmission sections of the motor to maximize precision, durability and reliability. These technologies include:

​

• Everwall: Improves motor efficiency through uniform distribution of wall thickness in the stator, which increases torque and durability.

• Hard Rubber: Offers a robust option that is better suited to severe conditions, reducing tortuosity and improving drilling stability.

These solutions can be customized to optimize rate of penetration (ROP), minimize slip distance and maintain wellbore quality, key factors to maximize the economic return of operations.

In short, the combination of innovative technologies and adaptation to the specific needs of each formation allows for significantly improved performance in directional drilling, giving operators greater control and efficiency in their projects.
