Abstract
A drilling assembly includes a particle adjusting mechanism upstream of a positive displacement motor. The motor includes a metal stator, a metal rotor at least partially disposed within the metal stator, and a motor gap defined between the sealing line of the metal rotor and the lobes of the metal stator. The particle adjusting mechanism adjusts a solid particle condition of a media flowing therethrough into a treated condition in which any remaining solid particles will travel through the motor gap without widening the motor gap to a failure gap size that causes the metal rotor to lock up or to rotate inefficiently slow. The particle adjusting mechanism adjusts the solid particle condition by removing, reducing a size, reducing a dimension, deforming, modifying a shape, dissolving, or chemically reacting at least a portion of any solid particles contained in the media. The drilling assembly is suited for high temperature wellbores.
