Measurement of Ultrasonic Attenuation Coefficient of Mud

Abstract:

Article Preview

Ultrasonic attenuation coefficient of media phase is an important parameter in process tomography by amplitude method. At normal temperature (25°C), the experiment adopts continuous pulse string with the frequency of 0.5 MHz to measure ultrasonic attenuation coefficient of mud (average particle size about 300µm; water content 17%; mud-sand ratio 1:9). By the formula α= (1 / Z) 20lg (P0 / PZ), the attenuation coefficient of mud is calculated to be about 4.26×10-1dBcm – 1.
