activation logging 活化测井一种测井技术。用中子照射辐射仪器附近的地层,使一些原子核变成放射性同位素。原子核活化所产生的特定的放射性同位素,可根据其特征的次生放射性和随时间而衰减的方式加以确定。这就提供了识别地层中原来存在的元素的一种手段。见induced spectral gamma-ray log。
activation logging A logging technique. Neutron irradiation of radiation near the formation of the instrument, so that some nuclei into radioactive isotopes. The specific radioactive isotopes produced by nuclear activation can be determined by their characteristic secondary radioactivity and decay over time. This provides a means of identifying the elements that were originally present in the formation. See induced spectral gamma-ray log.
