【摘要】 常规算法是通过计算主测线和联络测线的相干系数,然后取几何平均作为分析点的相干系数。本征值相干技术是一种定量化计算波形相似性的一种方法,它是通过在时空中定义"全局化的"孔径,并综合地层倾角和方位角的计算来实现。实际地震数据处理的结果表明:在揭示构造及地层的细节特征方面,该方法要优于传统的常规算法,同时还保持了其计算的效率。更多还原

【Abstract】 Conventional algorithm is through the coherent coefficient of main line and tie line to derive average geometric values as coherent coefficient of analytic points. The characteristic value of coherent technique was method for calculating the waveform similarity quantitatively, it was calculated through globalization defined in space-time domain and by combining formation dip angle and azimuth. The result of seismic data interpreting shows that for denoting the characters of structures and stratum, the method is optimal than the traditional one with high calculating efficiency.更多还原
