Method for measuring the propagation velocity of ultrasonic acoustic waves through rock fragments

摘要

The present invention relates to a method for measuring the propagation velocity of compressional and shear ultrasonic acoustic waves through rock fragments, coming directly from the drilling of wells in the oil industry and having dimensions of even less than one centimeter in diameter, said method comprising passing the acoustic waves through the fragment of interest and measuring their transit time, after inserting the said fragment between two appropriate piezoelectric transducers.
