摘要
对核测井伽马能谱探测器的测量不确定度进行评定,建立了数学模型,找出构成测量不确定度的要素和分量组成,分析得出探测器的能量分辨率为8.958%,相对合成标准不确定度为1.065%,k=1。按照评定结果判断,探测器可以保证伽马能谱测井仪的正常使用。
Measurement uncertainty of gamma-ray detectors for gamma spectrum logging were evaluated,and established a mathematical model to identify the elements constitute about the measurement uncertainty,resolution was 8.958%,the relative combined standard uncertainty was 1.065%,k=1.According to evaluation result,detector would be normally made use of gamma spectrum logging tool.
