Description
Agitator: reduce friction and solve pressure drag,improve weight
transfer，increase drilling speed, stable
toolface,save drilling cost. Available size is
*3mm,*5mm,**0mm,**7mm,**5mm,**2mm,**3mm,**4mm.
Agitator Drilling Principle:
1 drill fluid drive rotor rotate high speedly.
2 rotor rotate valve and static valve move and coincidence.
3 Periodic changes in the flow area through the valve plate.
4 Generating periodic pressure pulses.
5 By periodically acting on the spring of the upper vibrating end,
a periodic compression release of the spring
is formed, which translates into a periodic oscillating force and a
tool amplitude.
6 Improve the pressure transmission and drive the drill pipe which
stick on well wall move to relieve the
pressure drag.
Agitator Function:
1 Improve the effect of downhole drilling pressure transmission
2 Effectively increase the rate of penetration
3 Significantly reduce friction
4 Compatible with MWD / LWD
5 Good fit with all kinds of drill bits
Current Market Situation:
According to the market, at present, agitator tools are widely used
in Xinjiang, Sichuan, Bohai and Nanyang,
and agitator are proved can effectively increase the rate of
penetration.
