magnetic screen скважинных geophysical instruments

摘要

the utility model relates to a geophysical exploration wells, specifically to the apparatus of neutron log.magnetic screen contains the block detector, which are сцинтилляционный crystal and фэу, implemented in the form of a cylinder of steel with high magnetic porous walls 2–10 мм,the фэу in whole length in several layers намотана band of магнитомягких alloys 0,5–1,5 mm total thickness.the role of magnetic screen фэу can perform submarine hull geophysical equipment made of steel with high magnetic porous.the technical result is to increase the sustainability of equipment to the magnetic fields. 1 il.
