SYSTEM FOR CONTROLLING OIL WELL DRILL DYNAMICS

摘要

A system is provided to control oil well drilling dynamics. The system includes a plurality of downhole sensor modules, which, when distributed along and coupled to a first portion of a drill string detect a lumped parameter of a second portion of the drill string. Each downhole sensor module produces a sensor signal. The system further includes one or more controllable element modules, which, when distributed along and coupled to a third portion of the drill string affect the lumped parameter of the second portion of the drill string, each controllable element module being responsive to a controllable element signal.
