自然伽马能谱测井能把自然放射性中的铀、钍、钾同位素有效地区分开来,利用U、TH、K三条分量曲线较好的解决了NDx井岩性识别、计算地层中的泥质含量、识别高自然伽马放射性储层、定性分析地层沉积环境、评价生油岩的问题。
Natural gamma ray spectrometry logging can effectively differentiate uranium, thorium and potassium isotopes from natural radioactivity, and using the three component curves of U, TH and K to well solve the lithological identification of NDx wells and calculate the argillaceous Content, identification of high gamma ray radioactive reservoirs, qualitative analysis of sedimentary environment, evaluation of source rocks.
