APPARATUS FOR RECEIVING DOWNHOLE ACOUSTIC SIGNALS

摘要

The invention relates to an apparatus for receiving downhole acoustic signal s, processing the signals into electric signals, then transmitting the signals wirelessly to a remote above-surface monitoring station. The apparatus is mountable to an above-surface rotatable component used in borehole application. The apparatu s includes an instrument housing, and a clamping assembly attached to the housing and having sufficient length and flexibility to enable the apparatus to surround the perimeter of the rotatable component.
