Abstract
The operating dynamics of a high-speed borehole seismic source of unbalanced type was studied on a test bench in laboratory conditions. The inner chamber of a vibration source was filled with liquid and the unbalance in it was spun by an electric drive with a rotation frequency from 10 to 50 Hz and a step of 5 Hz. A comparison of vibration amplitudes generated by a vibration source with a dry and a liquid-filled inner chamber is made.
