DEVICES, SYSTEMS, AND METHODS FOR REDUCING MAGNETIC PARTICLES IN A FLUID FLOW

A downhole motor includes a primary fluid path between a housing and a rotor and a secondary fluid path between the rotor and a stator. Fluid is diverted from the primary fluid path through a secondary inlet to the secondary fluid path to lubricate the motor. A magnet is located proximate the second...

Beschreibung
Zusammenfassung:	A downhole motor includes a primary fluid path between a housing and a rotor and a secondary fluid path between the rotor and a stator. Fluid is diverted from the primary fluid path through a secondary inlet to the secondary fluid path to lubricate the motor. A magnet is located proximate the secondary inlet to bias magnetic particles in the drilling fluid away from the secondary inlet. Un moteur de fond de trou comprend un circuit de fluide primaire entre un boîtier et un rotor et un circuit de fluide secondaire entre le rotor et un stator. Le fluide est dévié du circuit de fluide primaire à travers une entrée secondaire vers le circuit de fluide secondaire afin de lubrifier le moteur. Un aimant est situé à proximité de l'entrée secondaire pour solliciter des particules magnétiques dans le fluide de forage à distance de l'entrée secondaire.
