DRILLING FLUID PROPERTIES CONTROL FOR PDC BIT DRILLING

    Graphical Abstract
    • Abstract
  • PDC bit have advantages of high penetrate rate,long bit life which saving tripping times so that the application of PDC bit can improve drilling efficiency. PDC bit application effect are limited by short tripping time to avoid borehole underguage during drilling, drilling rate always decreased after short tripping. Though improving mud properties such as mud cake, the PDC bit tripping problem have been solved, without short tripping.
