Abstract

Det er vist et sanntidstelemetrisystem for bruk med et boresystem innbefattende en rotasjonsventil (28) som styrer tilførselen av borefluid eller -slam til et brønnverktøy. Systemet omfatter mottak av data som skal overføres, omkoding av dataene som en varighet, og styring av rotasjonsventilens (28) rotasjon, slik at rotasjonsventilen (28) roteres for nevnte varighet med en forutbestemt rotasjonshastighet for å bevirke dannelse av trykksvingninger eller -bølger i borefluidet eller -slammet.A real-time telemetry system is shown for use with a drilling system including a rotary valve (28) which controls the supply of drilling fluid or sludge to a well tool. The system comprises receiving data to be transmitted, recoding the data as a duration, and controlling the rotation of the rotary valve (28) so that the rotary valve (28) is rotated for said duration at a predetermined rotational speed to effect formation of pressure fluctuations or waves in the drilling fluid. or sludge.
