Impact to drill collar, drill rod telemetry system (LWD), measurement-while-drilling system (MWD), with bit pressure power temperature measurement system (PTWD) and
The valuableness drilling equipment bring harm such as drill bit is especially prominent.First from drill assembly and exciting source in live actual mechanical process
Angle control vibration avoids resonant frequency by preferred drilling parameter and change drill column structure, and most effective means are exactly to pacify
Fill damper.There are two types of common dampers, and one is spring damper, core component is disk spring, and core is former
Reason is that , Dan Praise compression generation mechanical friction absorbs bit pressure when bit pressure is excessive, the spring elongation release energy when bit pressure is too small
It measures to drill bit；Another kind is hydraulic buffer, and principle is to realize vibration damping by changing the volume of hydraulic oil.Both dampers
Universal disadvantage is that structure is complicated, and tool is perishable, and damping parameter range is small, and control ability is fixed, and does not have vibration damping to thump
Effect.
