Overview

Analysis combines single-phase CFD to assess bearing capacity and evacuation depth of Polycrystalline diamond compact bits, indicating risks of broaching.

Key Points

  • Bearing capacity is assessed to determine risks related to broaching in conductor jetting contexts.
  • Evaluation incorporates factors like bit eccentricity and nozzle layout to influence evacuation depth.
  • Analysis utilizes single-phase CFD model combined with analytical formulas to enhance understanding of jetting behavior.
  • Results underscore the importance of thorough evaluation for safe and effective conductor operations in marine drillings.
