Description

Agitator can increase the effectiveness of weight on bit transfer by axial vibration itself in the process of drilling, can reduce the friction resistance between the bottom of the drill and drill hole,can be applied in all kinds of drilling mode to improve the rate of penetration. The axial vibration of Agitator is continuous and soft,different with the conventional rotary drilling in form. That is to say,to make the bit pressure of conventional rotary drilling change continuously and softly as the sine rule.

Major Functions:
1.To reduce the friction between the drilling tool and the wall by producing the axial vibration.
2.To improve the control for tool face and increase the rate of penetration by the match with steering drilling motor.
3.When combining with conventional turntable, increase the rate of penetration and lifetime of bit by reducing the harm of Stick-Slip in drilling process.
4.To increase the attainable depth of horizontal well, multilateral well, coiled tubing/through tubing.
