Downhole Seismic Velocity logging Survey System Shear Velocity Measurement with Geophone

Downhole Seismic Velocity logging Survey System Shear Velocity Measurement with Geophone

The wave velocity test is suitable for determining the wave velocity of compression waves, shear waves or Rayleigh waves of various rock and soil bodies. The single hole method, cross hole method or surface wave method can be used according to the task requirements. The iron ball is used to hit the wooden board horizontally to cause movement between the board and the ground, which generates rich shear waves, so as to receive the shear waves propagating downward through the soil layer at different heights in the borehole. Because this vertical propagation path is close to the situation where natural formations propagate vertically upwards from bedrock, it is more useful for formation response analysis.
