●PDC 与牙轮切削轮廓匹配优化，发挥牙轮减扭、降扭作用，提高钻头滑动导向工具面可控性；

●切削结构力平衡设计分析，提高钻头工作稳定性，减少钻头粘-滑效应，增强钻头导 向性能；

●较短保径设计和主动与被动保径相结合，提高钻头造斜率、侧切性能和导向可控性；

●钻头多点规径、保径均衡定位与扶正结构设计，提高钻头稳定性，以及其在造斜、稳 斜钻进中的适应性。

·Optimization  of  PDC  and  roller  cutting  profiles  to  enhance  the  foller function  of  torque  reduction,improving  the  controllability  of  the  drill  bit's sliding guide surface.

·Analysis of cutting structure force balance design to improve the stability of the drill bit,reduce the stick-slip effect,and enhance the directional performance of the drill bit.

·Combination of shorter gauge design and active/passive gauge retention to improve the build-uprate,lateral cutting  performance,and  directional  controllability  of  the  drill  bit.

·Design of multi-point gauge and gauge retention balancing positioning and stabilization structureto improve the stability of the drill bit and its adaptability in directional drilling.
