摘要
介绍了一种随钻核磁天线的铁粉芯磁芯材料,该材料具备高饱和磁通密度,并具备较低的介电损耗,并具备高绝缘强度,并在强磁环境下不产生磁致伸缩效应,较好的解决了随钻核磁测井仪探头敏感区域设计需求.
Abstract
This paper introduces an iron-powder core material for nuclear magnetic antenna while drilling.The material has high saturation magnetic flux density,low dielectric loss and high insulation strength,and does not produce magnetostriction effect under strong magnetic environment.It can better meet the design requirements of the sensitive area of nuclear magnetic logging tool probes.
