摘　　要：根据不同分辨率测井资料在频域内的显著差异 ,利用位势理论及分形几何投影定理 ,实现了不同分辨率的相同和不同物理量测井资料间的分辨率转换。其中利用小波变换理论确定窗口 Fourier变换中窗口的大小和形状。结果表明 ,该套方法具有良好的实用性和广泛的普适性。Based on the prominent differences of logging data with different resolutions in frequency domain,we can realize resolution transformation among log data with same or different physical quantities of different resolutions by potential theory and fractal projection law.Among these, the wavelet transformation theory can be used to determine window size and shape in window Fourier transformation.The result obtained shows that the above method is practical and adaptable.
