THE RELATIONSHIP BETWEEN THE STRUCTURE PARAMETERS AND THE DRILLING PROPERTIES OF PDC CENTERLESS BIT

    Graphical Abstract
    • Abstract
  • The drilling properties of PDC centerless bit are in Close relationship with the structure parameters of the bit, After the orthogonal tests of PDC bits in laboratory and field, the optimum structure parameters of PDC centerless Bit were obtained.
