石油测井仪器的刻度标准化工作

On the Calibration Standardization for Petroleum Nuclear Logging Tools

回顾了中国石油测井仪器刻度标准装置建设的经过,阐明了标准装置对石油测井仪器在研发、应用等方面的重要意义。对石油工业测井计量站已建成的标准装置在国内石油测井仪器量值统一方面所起到的贡献作了阐述。旨在说明原石油部成立石油工业测井计量站的初衷,强调测井仪器刻度标准对石油行业的重要性,希望能够引起有关部门对测井仪器刻度及标准化工作的高度重视,适应中国石油国际化程度不断提高的形势需要。

This paper reviews the construction of the calibration standards ＆ calibration facilities for petroleum nuclear logging tools in China. Emphasized is the significance of calibration facilities to the research ＆ development of well logging tools and their applications. The standard calibration facilities （primary standards） constructed in Logging Metrology Center of Petroleum Industry in China plays an important role in tracing to the source system for nuclear logging tools. The processes of transference, comparison, calibration, testing, verification and inspection are conducted during the tracing to the source system. The establishment of such conversions is in order to ensure the measuring unit uniformity and the accuracy of log data. This paper is aimed at drawing special attention to calibration standards standardization for logging tools and a unified quantities ＆ units, adapting to the internationalization of China petroleum exploration ＆ development.
