Corrections of gamma-ray responses |
摘要 |
System and method for formation logging using a gamma-ray detector. The techniques including acquiring gamma-ray signals using the gamma-ray detector, the acquired gamma-ray signals having energies that span at least a first-energy region and a second-energy region, wherein the first-energy region includes energies higher than a selected threshold and the second-energy region includes energies lower than the selected threshold; determining interference signals based on the acquired gamma-ray signals in the first-energy region; and correcting the acquired gamma-ray signals in the second-energy region based on the interference signals to provide corrected gamma-ray signals. |
