A Soft Magnetic Material for LWD Magnetic Resonance Tool
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.
