摘要
许多研究认为,自然伽马曲线具有分形特征。根据实际资料,利用分形理论,对自然伽马曲线进行了分析,结果发现,自然伽马曲线的分形特征与地层中放射性富集程度有关,曲线的分形特征在一定的范围内存在,但当地层中放射性物质含量富集到一定程度时,就不具有分形特征。分形在自然伽马测井曲线中的适用性需要认真分析。
Many researchers hold that natural gamma-ray curves have fractal characteristics. Using the fractal theory, the authors studied some natural gamma-ray curves. The result shows that the fractal characteristics of the natural gamma-ray curves are related to the extent of radioactive concentration in strata. The fractal characteristics exist within a certain range but disappear when the radioactive concentration exceeds a certain value. The adaptability of fractal characteristics in natural gamma-ray curves should be carefully analyzed.
