Functional Modules

u Intra-tunnel excitation method: Intra-tunnel excitation method (spontaneous self-rewinding), that is, in-cave excitation and in-cave reception, without ground vibration source, accurate test of shear wave velocity;

U Splint method: use a heavy hammer to hit the ground vibrating plate or steel plate to test the shear wave and compression wave velocity of the formation;

u Low-frequency grounding pulsation excellent cycle test.

Logging probe:

self-excited probe: the upper part is the excitation source, and the lower part is two receiving detectors. The electromagnetic impact excitation source acts on the instantaneous impact force perpendicular to the wellbore wall, and collects and receives shear waves (S-waves, S-waves) that propagate along the shaft wall in the direction of particle vibration perpendicular to the shaft wall.

button probe: It adopts a three-component detector, electromagnetic automatic suction method to open the bracket, and control the host key to open at any time in the hole of any depth, and the non-mechanical opening. The probe is not resisted by mud too much, resulting in the probe not placed at the bottom of the hole to open the support, avoiding repeated operations to raise and place the probe, wasting time. To avoid mechanical opening, the probe must be placed at the bottom of the hole and the support should be opened by mechanical force.
