Tungsten Carbide Rotors And Stators Of MWD & LMD For Mud Pulser Used In The Oil And Gas Industry
Product detail
The rotor of the continuous wave pulse generator is equipped with a stator with the same number of blades as the rotor. When the rotor crosses the cross section of the rotor and the relative position of the overcurrent section of the stator, a continuous sinusoidal pressure wave is generated, which is encoded by the downhole probe. The measurement data is loaded by the modulation system, the change of the pressure waveform is detected on the ground, and the measurement data is calculated by decoding.

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.
