Study of gamma spectrometry and radioactive prospecting——taking example for Maoming oil shale mine in Guangdong

The spreading equilibrium ratio values indicate that disequilibrium may cause errors in U channel data obtained by ground gamma-ray surveying.

Using natural gamma-ray spectroscopy log method to determine clay mineral content;

The natural gamma-ray spectroscopy log method could not only identify the types of the clay mineral, but also determine the content of the clay mineral in the reservoir.
