Drilling damper udb 203
The device is designed to increase the drilling tools and elements life period, improving their operation resulting from:
1. Smoothing of axial shocks in the process of tools running-in, after making tools connections, and in the event of intermittent tool feed.
2. Absorption of the axial vibration energy, if it occurs from the positive displacement motor to the bit, and from the bit to the drilling string elements
