JET TEST STUDY ON SINGLE JET NOZZLE OF PDC DRILLING BIT IN COAL EXPLORATION

    Graphical Abstract
    • Abstract
  • Based on the jet test of jet nozzle,the relationships between the dimension of jet nozzle of drilling bit and jet distance and the dynamic pressure of jet flow are studied,the optimal jet texture parameters are obtained.
