摘要
为解决坚硬岩层钻进效率低下,研究设计一种复合胎体金刚石钻头,在软岩层进尺快,在硬岩层亦能获得相对较高的钻进速度,突破了单靠降低胎体硬度的传统设计理念,获得了满意钻进效率。
In order to solve low drilling efifciency in the hard rock, we design a composite matrix diamond bit, headway fast in soft rock, also can achieve a relatively high drilling speed in hard rock. Those break through the traditional design concept by lower matrix hardness, obtained satisfactory drilling efifciency.
