| Abstract: | In the paper the force on rock granule and the starting conditions about the mud block problems during running of the PDC petroleum drill is introduced and the corresponding calculating model is built up. The distribution of velocity field of oil well can be got by computer simulation, and it gives the theoretical basis for research on the capability of cleaning up the scraps and effective restraining the mud block generation during drilling. |
