This article introduces the new logging method which uses Gadolinium-injecting instead of Boron-injecting and uses Neutron-GammaLogging instead of Neutron Lifetime Logging.
文章介绍了注钆代替注硼，中子伽马代替中子寿命的测井方法，对其优点作了分析，并列举了一些实例。

Sealed neutron source and gamma source used in nuclear logging have strong radioactivity which is harmful to operators.
核测井使用的密封中子源和伽马源具有较强的放射性，对操作人员有一定的辐射损伤。
