自然界中存在着很多能够产生连续的幂指数频谱的自然现象,这些现象将不具有特征频率,而且在很宽的范围内是标度不变的.本文根据对应原理,把测井相随深度关系,看成一种时间序列,进行频谱处理,发现测井相功率谱密度与波数在双对数坐标下呈现良好的线性关系.其斜率值β经过换算对应于测井相的分维数D,通过对八盘峡地区25口井的中子及密度测井数据的处理分 There are many natural phenomena in nature that can produce continuous power exponent spectrum, which will not have the characteristic frequency and scale to a very large extent.In this paper, according to the corresponding principle, , Which is treated as a time series and processed by frequency spectrum.The results show that there is a good linear relationship between logarithmic PSD and wave number in double logarithmic coordinates.The slope value β is converted to the fractal dimension D The treatment of neutron and density logging data of 25 wells in Bapanxia area
