查询词典 loudspeaker cone

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.
