摘要
用热中子俘获瞬发伽玛能谱分析试样中元素的含量和地层元素测井,均涉及元素测定“灵敏度”的概念。本文研究了国内外所用的“灵敏度”计算公式后,提出中子俘获瞬发y能谱地层元素测井“理论灵敏度”和“实际灵敏度”的概念,并给出计算公式。
To analyse the element contents and the formation elements in samples with thermal neutron-capture transient γ-spectrum involves the element measuring 'sensitivity'. The concept of 'theoretical sensitivity' and 'practical sensitivity' of neutron capture transient γ-spectrum formation element logging and its calculation equations are given after studying the 'sensitivity' calculation equations both at home and abroad.
