Remote Control Technology in Intelligent Oil-Well Based on Acoustic Wave

Abstract

In this paper, we investigate an acoustic remote control technology through the annulus channel in an oil-well. To establish a reliable communication, we first evaluated the acoustic charateristic of the aunnulus channel through field experiments. Then, a remote control system was implemented with a ground equipment serving as an acoustic source, and an underground equipment used as a receiver. A demonstrative experiment, in which we succeded in remoting an intelligent valve over 1257 m, has been presented to verify the proposed technology.
