本文通过大量的试验数据介绍了DEL金刚石增强复合齿的性能、特点和优越性。DEI楔形齿－改传统保径齿的被动保径状态。通过优化金刚石的成份，增强齿的强度和韧性，修改现有碳化钨齿的几何形状，从而产生了新一代的进攻型金刚石增强保径合金齿。提高了钻头的保持井径的能力，更可靠地保持了钻头的切削结构，延长了钻头的保持机械钻速的时间，使钻头的使用寿命更长，完井时间更短。
In this paper, the performance, characteristics and advantages of DEL diamond reinforced composite tooth are introduced through a large amount of experimental data. DEI wedge teeth - to change the traditional gage tooth passive gage state. By optimizing the composition of the diamond, increasing the strength and toughness of the tooth, modifying the geometry of the existing tungsten carbide teeth, a new generation of aggressive diamond enhanced gage teeth was created. Improve the drill bit’s ability to maintain the caliper, maintain the bit’s cutting structure more reliably, and prolong the bit’s holding time of the mechanical drilling speed, which results in a longer service life of the bit and a shorter completion time.
