摘要
DKY95XHPS型地勘牙轮钻头采用了楔形硬质合金镶齿、滑动轴承密封润滑、储油压力平衡补偿和新型专利喷嘴等先进结构，使用该钻头及配套无岩心钻进工艺，在中硬砂岩和灰岩中钻进，钻探台效提高，单位进尺成本降低。
Wedge tungsten carbide inserts, sliding and sealed bearing, compensation system of lubricant and a new patented nozzole have been considered into the design of DKY95XHP5 geological cone bits. It will result in higher efficiency per rig. month and lower cost per footage using the drill bit and full face drilling technology in medium hard sandstone and limestone.
