摘要
为提高复合片在软岩钻进中的效率及寿命,提出了改变复合片切削齿形状,运用新的布齿方式和新的保径设计,设计制造的Φ76 mmPDC钻头在软岩钻进中取得了良好的效果。详细介绍了该软岩钻头的结构设计及现场应用效果。
To increase the drilling efficiency and prolong the service life of PDC bit for soft rock drilling,suggestion was made to improve the cutting tooth,take new tooth arrangement and new diameter retention design.Good drilling effect was achieved by the developed 76 mm PDC bit and the paper introduced the soft rock bit structure design and on-site application effect in detail.
