2024石油专用补偿中子刻度器校准规范试验报告

《石油专用补偿中子刻度器校准规范》试验报告试验日期和地点：试验日期：2023年6月试验地点：石油工业测井计量站校准实验室试验目的：通过试验在理论上，了解补偿中子刻度器孔隙度标称值的量值溯源与传递关系，在实践上，掌握补偿中子刻度器孔隙度参数的校准，以及校准的操作要领、基本步骤和方法。三、试验设备及环境要求：试验设备：补偿中子标准井、补偿中子量值传递仪器、补偿中子刻度器环境要求：环境温度：5℃～35℃。相对湿度：RH<80%。其它要求:无其他放射性干扰，无强震动、无强电磁干扰。四、试验内容：通过将装源后的补偿中子量值传递仪器放入补偿中子标准井中，记录仪器在标准井中测量的长源距计数率、短源距计数率。将仪器依次放置到其它标准井中进行如上操作，建立补偿中子量值传递仪器长、短源距计数率与孔隙度值的响应关系，并计算标准不确定度。将装源后的补偿中子量值传递仪器放置于待校准刻度器的各测量点进行测量，记录各测量点测量的长源距计数率、短源距计数率，并根据计算测量点的比值计算孔隙度值和标准不确定度。五、试验记录数据：（一）补偿中子量值传递仪器稳定性试验记录表表1补偿中子量值传递仪器稳定性试验记录表送校单位：石油测井仪器计量站测试时间2023.6.21温度：27℃湿度（RH）：40%井号23量值传递仪器型号行业标准井地面检定系统
