Working principle ▍

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

The buckle plate method isKnock on the shock plate on the ground, and after exerting an impact force on the underground, there will be a P wave along the strata of the well wall.And the S wave propagates down. When the P wave and S wave propagate to the position of the wave detector, the wave detector can convert the initial time and vibration waveform of the P wave and S wave into electrical signals and record them by the instrument. The hammering method is used to test the shear wave velocity, that is, the vibration plate is placed next to the ground drilling. The general size of the vibration plate is25*25*120(Cm), and the load is 400kgThe left and right heavy objects are hammered at both ends of the positive and negative two-way hammering plate, so as to produce positive shear and reverse shear waveforms, so as to calculate the wave velocity.

Well logging probe ▍

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.

KB30Buckle plate probe: adopts a three-component wave detector, and the electromagnetic automatic suction method opens the bracket. Any depth in the hole can be opened by the host button control at any time, non-mechanical opening. The probe is not too resistant to mud, resulting in the fact that the probe is not placed at the bottom of the hole to open the bracket, avoiding repeated operation and placing the probe, and wasting time.To avoid mechanical opening, the probe must be placed at the bottom of the hole and the bracket must be opened by mechanical force.
