刻度对补偿密度测井仪测量值的影响

The effects of calibration on the compensated density logging measurement

由于补偿密度测井使用的伽玛放射源对人体和环境危害较大,一般要求测井一次成功,所用的测井仪器要有较高的测量准确度和稳定性。文章针对密度测井仪器的性能和仪器的刻度方法,提出了提高补偿密度测井质量的刻度验证法,并给出了应用实例,结果证明该方法对提高测量准确度是行之有效的。

The gamma source used in compensation density logging does a lot harm to human health and the environment,so generally the job should not be done more than once,and logging instrument are required to be accurate and stable.In view of the density logging instrument performance and instrument calibration method,This article proposes the method of increasing compensation density spectrometer logging quality scale validation.An application example is given,and the result proves that the method is effective to improve the measurement accuracy.
