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 act underground.OneAfter the impact force, P waves and S waves propagate down along the well wall strata. When the P waves and S waves propagate to the position of the wave detector, the wave detector can convert the initial arrival time and vibration waveform of the P wave and S wave into electrical signals and record them by the instrument. Use the hammering method to test the shear wave velocity, that is, next to the ground drillingPlace the vibration plate,The size of the general vibrating plateFor25*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.

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.

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, so the probe is not placed.Open the bottom of the holeBracket, avoid repeatedly operating and placing the probe, which is a waste of time.Avoid mechanical opening. The probe must be placed at the bottom of the hole, relying on the machine.Force to openBracket.

ZB100Sound wave well logging probe: The sound wave test is a double-retracted underground transducer, which is sent to receiveOneSpacing 30 centimeters, ReceiveOneTo receive 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.
