Improvements in the methods for interpreting diagrams recorded with the SGDT-2 device

Nomograms are constructed and described suitable for the unified presentation of the already used pallets and permitting the processing of the data of the borehole-mounted gamma-defectometer with the aim to determine substance density in a tube-exterior space and column eccentricity in a borehole. The processing of the cementograms with the aid of the improved method reduces to minimum preliminary calculations. It is also possible to cut down the processing time by several times
