Working principle ▍

Acoustic well loggingYesWhen the waves formed after the exciter vibrates, they spread along the well liquid to the well wall (rock body). At this time, the wave with an angle of incidence greater than the critical angle forms a refraction wave, which first reaches the first line of the pick-up and then reaches the second channel of the pick-up. At the same time, the host recorded the whole process of vibration of the first and second channels of the pickup. According to the analysis of the wave chart, the first to reach the first and second channels of the receiver was the longitudinal wave.

The sound wave test is a double-retracted underground transducer, which is sent to receiveOneSpacing 30 centimeters, Reception one to reception two spacing30cm. Collect the first waveform and automatically read the starting jump point to determine the beginning time of the longitudinal wave, and calculate the longitudinal wave velocity.
