SENSOR-BASED CONTROL OF VIBRATIONS IN SLENDER CONTINUA, SPECIFICALLY TORSIONAL VIBRATIONS IN DEEP-HOLE DRILL STRINGS |
摘要 |
<p num="1">Control device (100) controlling a drilling operation and methods by which the dynamics of the continuum in question can be divided into superimposed waves, of which the wave traveling in the direction of the actuator and/or drive (10) is compensated by the actuator. This prevents reflection of the energy on the actuator. By using two sensors (30, 40) the wave traveling towards the actuator (10) and the wave traveling away from the actuator (10) can be calculated separately from one another, so that both the parameters of the wave traveling toward the actuator and the parameters of the wave traveling away from the actuator can be determined in order to be able to perform a control of the driving device of the drill string (20) on this basis.
