WELL SYSTEM, METHOD FOR TESTS IN DOWNHOLE TOOL, AND EQUIPMENT FOR TESTING AND ADJUSTMENT OF DOWNHOLE TOOL

摘要

FIELD: physics, measurement.;SUBSTANCE: invention concerns equipment for automatic resonance frequency detection in a well system. Well system includes downhole tool for operation in multiple frequencies and drive system controller changing operational frequency of downhole tool during test. Controller defines resonance frequency of downhole tool automatically.;EFFECT: reduced time for defining resonance frequency and equipment cost.;21 cl, 2 dwg
