Abstract
The system of metrological support of geophysical well surveys (GWS) is a system of technical and methodological tools ensuring unity, reliability and accuracy of measurement results. For acoustic logging devices, physical standards with highly stable properties were developed and implemented. They are based on simulation of attenuation and time delay of elastic waves propagating in casing pipes. The design of a calibration device for acoustic video logging equipment made it possible to increase research reliability. The design of a field calibration device allowed for rapid calibration of acoustic equipment in field conditions for improving the GWS quality.
