【摘要】 针对复杂断块的断裂地震特征,笔者利用超道构建技术,并与基于小波变换的相干技术集成,再进行相干计算。超道构建技术具有不改变地层的原有信息而保留了地层的倾角特征、降低属性分析的平均效应的优势,试算结果证明,该方法不仅计算速度快,而且抑制噪声能力强。通过与传统相干算法实际应用对比,该算法有效地突出了地层的高连续性特征,提高了识别断层的分辨率,地质特征信息丰富,有利于断层解释,尤其适用于低信噪比地震资料地区。更多还原

【Abstract】 On the basis of the seismic reflection and fault characteristics,this paper deals with supertrace-based coherence-estimation technique for complex fault interpretation and the actualization of this technology.To include more seismic traces in the coherence estimation,this paper introduces a supertace technique that constructs a new data cube by rearranging several adjacent seismic traces into a single supertrace.And the cube preserves the dip information contained in the original data cube,and reduces average effect of seismic attributes computation.By combining the supertrace technique with the wavelet transform of seismic coherence technology,the coherence value is estimated.The method has very fast calculating speed and can effectively suppress Gaussian noise.The result shows that this method is significant in comparison with the routine method.It can effectively enhance the faults continuity,which is helpful to trace strata and explain faults.It is especially adapted to low SNR seismic data structure interpretation.更多还原
