Spectral gamma-raylog has given a quantitative interpretation method for associated sandstone uranium deposit in Qianjiadian Sag, peripheral Miocene basin of Liaohe oilfield.
对辽河油田外围中生界盆地钱家店凹陷油气伴生可地浸砂岩型铀矿伽马能谱测井提出了定量解释方法。

The gammaray index is usually computed from a well log such as a gammaraylog.
自然伽马指数通常由自然伽马或其它测井曲线计算得到。

For some sandstone reservoirs with high natural gammaray existed in Ordos Basin, it is difficult to be correctly identified and to calculate its shale content with gammaraylog only.
