| Abstract: A suppression module, a suppression assembly, and a drilling tool are
disclosed. The suppression module includes a spindle having a first end
and a second end, an ear plate slideably disposed between the first end
and the second end, a spring positioned between the ear plate and the
first end, and an activation mechanism coaxially disposed around the
second end of the spindle. The activation mechanism engages the ear
plate, activating the spring, or disengages the ear plate, deactivating
the spring. The suppression assembly includes at least two suppression
modules in series coupled to a processor. The suppression modules are
activated or deactivated by the processor, each of the suppression
modules being activated or deactivated independent of the other
suppression modules. The drilling tool includes a drill pipe, a drill
bit, a vibration sensor, and a suppression assembly between the drill
pipe and the drill bit. |
