Good Abrasion And Corrosion Resistance Tungsten Carbide Rotors For
MWD Pulse Head
Detailed Product Description:
Measurement-while-drilling (MWD) and logging-while-drilling (LWD)
use sensors to collect parameters such as the working status of the
drilling tool and borehole trajectory in real time, and transmit
the information to the analysis system, thereby providing real-time
operation guidance for the drilling engineer.
This product is mainly used for vertical well drilling tools, pulse
drilling tools, hydraulic oscillators, logging while drilling and
MWD drilling tools. It has the functions of diversion, erosion
resistance and mud sealing, and can indicate mud pressure and pulse
signals.
Product Feature :
1. Excellent abrasion resistance
2. High wear resistance
3. High fractural strength
4. high thermal conductivity
5. Small heat expansion co-efficient
Working principle :
The inclinometer pulse generator is inserted into the current
limiting ring through the control (mushroom head) gap to change the
annulus cross-sectional area therebetween. The mud pressure flowing
in the drill pipe is changed to form a positive mud pressure pulse
to realize signal transmission. The mud pressure flowing in the
drill pipe is changed to form a positive mud pressure pulse to
realize signal transmission. The pulse generator is driven by an
electromagnetic mechanism to control a small control valve, thereby
changing the pressure contrast of the upper and lower end faces of
the piston. Then use the pressure generated by the mud flow to push
the piston up and down, and the lifting rod (mushroom head) is
intermittently inserted into the restrictor ring to form a positive
mud pressure pulse.
