自然伽马测井曲线校正 gamma ray correction
应用岩心地面自然伽马曲线与测井自然伽马曲线对比法对岩心进行归位，进而对岩心样品进行深度校正，在很大程度上提高了岩心资料的准确性。
Contrasting core ground gamma curve with logging gamma curve locate the core, and then emend the depth of the core sample, which improve veracity of the core data.
根据这个变化，自然伽马曲线在开发测井中不但可以用于深度校正，而且还可以在诸如水淹层解释、吸水剖面测试、油水井验窜、找漏等方面进行应用。
According to this changing, natural gamma curve in development logging can be not only rectified in depth, but also used in some fields such as interpretation of water -...
