提高521补偿密度测井仪器刻度的准确性

Improvement of the calibration accuracy of 521 compensation density well-logging tools

通过对521补偿密度测井仪器的结构、仪器放射性原理的阐述,指出了影响仪器刻度精度的几种因素,包括仪器结构、泥饼、仪器的刻度装置、仪器的刻度过程,以及如何克服这些不利因素,提高521补偿密度测井仪器刻度的准确性所采取的方法。

The paper first introduces the structure and the principle of 521 compensation density well-logging tools,then points out several factors that influence the tools'calibration accuracy,such as the structure of the tools,the mud cake,the calibration device and the calibration process.It also discusses the measures for overcoming these adverse factors and improving the tool's calibration accuracy.
