1.Using new surface wear-resistant materials, more effective use of  positive and       negative ions to prevent mud packs more effectively.
Optimize the structure design, increase the narrow area in the bit design, deepen the waterway, and reasonably improve the blade thickness, so as to maximize the flow area in the use of the bit and improve the chip removal ability of the bit.
By using the bottom hole simulation and nozzle optimization design, the number and position of nozzles can be reasonably arranged to prevent mud balling more effectively.
