Abstract

Nedihullsverktøy kan styres ved bruken av et signal som er kodet på en akustisk bølge som blir sendt gjennom en rørledning til en nedihulls transiver som mottar signalet og er koplet til verktøyet. Likeledes kan data fra nedihullssensorer føres tilbake til overflaten kodet på akustiske bølger sendt gjennom rørledningen. I begge tilfellene tilveiebringer den foreliggende oppfinnelsen apparatet som er nødvendig for å kode signalet og føre dette inn i rørledningen ved hjelp av en piezoelektrisk stabel.Downhole tools can be controlled using a signal encoded on an acoustic wave which is transmitted through a pipeline to a downhole transceiver which receives the signal and is connected to the tool. Likewise, data from downhole sensors can be traced back to the surface encoded on acoustic waves transmitted through the pipeline. In both cases, the present invention provides the apparatus necessary to encode the signal and input it into the pipeline by means of a piezoelectric stack.
