岩性密度测井仪可以同时测量地层密度和岩性,目前在油田得到广泛应用。本文结合530快速测井平台系统岩性密度测井仪器的研制经验,介绍了岩性密度测井仪器和刻度过程,重点介绍了主刻度方法。 Lithology densitometers can measure formation density and lithology at the same time and are now widely used in the field. In this paper, based on the research and development experience of lithology density logging tool of 530 rapid logging platform system, lithology density logging instrument and graduation process are introduced, and the main graduation method is introduced emphatically.
