查询词典 auger drill

Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。
