The use of new surface wear-resistant materials, more effective use of positive and negative ions to prevent mud bags more effectively. Optimize the structural design, increase the narrow area in the bit design, deepen the water channel and improve the blade thickness reasonably, so as to maximize the flow channel area of the bit and improve the chip removal ability of the bit. Using bottom hole simulation and nozzle optimization design, reasonably arranging the number and position of nozzles can prevent mud pack more effectively.
