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.
在砂泥岩剖面中，泥岩往往比砂岩具有较高的自然伽马值，从而可以利用自然伽马测井将砂岩储层划分出来。
Based on the features of mudstone with higher gamma ray than sandstone in sandstone -mudstone section, we can distinguish sandstone reservoir from the drilling profiles with gamma ray log.
自然伽马测井测量的是地层总的自然伽马放射性，是套管井测井的一种最基本的方法。

对鄂尔多斯盆地存在的高自然伽马砂岩储层，仅用自然伽马测井资料难以正确识别并计算其泥质含量。
For some sandstone reservoirs with high natural gamma ray existed in Ordos Basin, it is difficult to be correctly identified and to calculate its shale content with gamma ray log only.
自然伽马指数通常由自然伽马或其它测井曲线计算得到。
The gamma ray index is usually computed from a well log such as a gamma ray log.
自然伽马测井是套管井测井中一种最基本的方法。它以地层自然放射性为基础，测井时用伽马射线探测器沿井眼进行测量。地层中的自然伽马放射性不是一成不变的。
Natural gamma logging is a kind of most basic methods of well logging in cased Wells which measure with gamma ray detector along well during logging.
