DIFFERENTIAL PRESSURE EFFECTING PDC BIT ON PENETRATION RATE

    Graphical Abstract
    • Abstract
  • This paper introduce analyzing work about pressure difference effect PDC bit on penetration by statistica1 analysis of drilling data.Analysis result shows that penetration of PDC bit decreases with difference increase and its decrease value larger than one of cone bit,due to penetration of PDC bit are higher than one of cone bit by 2 to 3 times.
