一、引言目前,在勘探和开发放射性矿床、石油和其它有用矿藏的工作中,已广泛地应用自然伽(亻馬)測井。一般地說,在这些工作中,不仅需要根据自然伽(亻馬)測井曲线确定目的层的厚度及深度,而且在确定矿层的放射性元素合量、貯油层的合泥量与渗透率等工作中,还必須根据自然伽(亻馬)測井曲綫确定代表地层放射性的真正曲线幅度值。但是,由于測量速度v I. INTRODUCTION Natural gamma-ray logging has been widely used in the exploration and development of radioactive deposits, petroleum and other useful minerals. In general, in these efforts, not only the thickness and depth of the target layer need to be determined based on the natural gamma logging data, but also in determining the amount of radioactive elements in the ore layer, the amount of clay in the reservoir, and the permeability It is also necessary to determine the true amplitude of the curve representing the radioactivity of the formation from the log of the natural gamma ray. However, due to the measurement speed v
