METHODS AND SYSTEMS FOR DOWNHOLE TELEMETRY

摘要

FIELD: physics; geophysics.SUBSTANCE: invention relates to geophysics and can be used in logging operations. Disclosed are methods and systems for downhole telemetry using a device configured or designed for deployment in a drilled well which crosses an underground formation. The device includes a downhole telemetry unit, a surface telemetry unit and a line for transmitting data between the downhole and surface units, configured to designed to transmit data over one or more data transmission channels using at least one telemetry circuit selected from a plurality of telemetry circuits based on at least one downhole parameter.EFFECT: high quality of transmitting exploration data.26 cl, 7 dwg
