METHOD AND APPARATUS FOR DETECTING FLUID FLOW MODULATION TELEMETRY SIGNALS TRANSMITTED FROM AND INSTRUMENT IN A WELLBORE

摘要

An apparatus for detecting fluid modulation signals transmitted by an instrument in a wellbore includes a motion sensor coupled to a selected position on an exterior of a conduit coupled between a discharge side of a fluid pump and an inlet to a pipe string suspended in the wellbore. The instrument is coupled to the pipe string. A signal detector is in signal communication with the motion sensor.
