阐述了地层中的自然伽马能谱与泥质质量分数及阳离子交换量的关系，介绍一种利用自然伽马能谱确定泥质质量分数和阳离子交换量的方法．利用该方法分析了松辽盆地大庆地区、三肇地区３３口井９３４块岩心的自然伽马能谱与泥质质量分数和阳离子交换量的对应关系，给出了它们之间的定量计算公
The relationship between the gamma ray energy spectrum in the stratum and the mass fraction of shale and cation exchange is described. A method for determining the mass fraction of shale and the amount of cation exchange by using gamma ray spectrometry is introduced. Using this method, we analyzed the correlation between the natural gamma ray energy spectrum, the mass fraction of shale mass fraction and cation exchange capacity of 934 cores in 33 wells in Daqing area and Sanzhao area, Songliao Basin,
