| Abstract: | A physical model for the bottomhole crossflow hydraulics of tricone roller bits was developed under certain simplifications and hypotheses. Some tests was made in laboratory. The experimental reuslts showed that the bottomhole crossflow hydraulics can be expressed with this physical model. The model provides the foundation for the computational modeling for the bottomhole crossflow hydraulics. |
