Working principle ▍

ZD-A6The in-hole excitation wave velocity tester is a method to determine the wave velocity of the strata where the drilling is located by using the detector placed in the drilling to receive the arrival time of the S wave signal from the seismic source.

In the drillingTake the well fluid asThe coupling agent uses an electromagnetic excitation source perpendicular to the well wall to exert a momentary impact force, which produces two types of mass point vibration in the well wall strata. One is that the direction of mass point vibration is perpendicular to the well wall and propagates along the direction of the well wall, which is called S wave (shear wave, transverse wave); the other is that the direction of mass point vibration is the same as the direction of propagation, called P wave ( Compression wave, longitudinal wave).

The wave detector receives the vibration signal of the S wave and converts it into an electrical signal, and then transmits it to the computer. After processing the data of the signal, the computer uses the two-channel correlation analysis method to automatically calculate the time difference between the propagation of the S wave between the two wave detectors, thus calculating the propagation speed of the S wave between the two channels.

ZF110Self-excitation probe: the upper part is the excitation source, and the lower part is two receiving detectors. The electromagnetic excitation source is perpendicular to the well wall. The momentary impact force is used to collect the receiving mass point vibration direction perpendicular to the well wall, and the shear wave (S wave, transverse wave) propagates along the direction of the well wall.
