FIELD: oil and gas industry.
SUBSTANCE: method applied for signal transfer to measuring instrument in well shaft involves acceleration along measuring instrument axis in the specified acceleration profile. Pre-determined acceleration profile corresponds to the signal subject to transfer. Axial acceleration of measuring instrument is recorded, and signal from recorded axial acceleration is decoded. Signal recording system for measuring instrument in the well shaft includes accelerometer oriented along longitudinal axis of measuring instrument, and device for comparison of measurements made by means of accelerometer at least for one pre-determined acceleration profile.
EFFECT: easier signal transfer and simpler design.
