摘要
复杂储集层问题属地震勘探中难题,由于受地震信号频带及子波等因素的影响,往往难对其以分辨和识别,用最大熵伯格算法,在频率域对有效地震信号进行谱外推和谱整形从而达到实现时间域分辨率的目的,而不同于传统的伯格反褶积方法也无需提取子波,实例证明该方法对提高分辨率识别薄层有较好的效果。
It is difficult to describe the seismic complex reservoir in geophysics exploration and it is uneasy to discriminate seismic thin layer by the frequency limit of seismic signal and the effect of seismic wavelet.In the paper,we extrapolate and reshape the frequency spectrum by using the maximum entropy Burg algorithm to get the high resolution section in time domain.This method is neither the same as the traditional Burg deconvolution nor the same as other deconvolution method of extracting the seismic wavelet.It is showed that the method is effective to enhance the seismic resolution and discrimination for complex reservoir in Burg maximum entropy algorithm.
