摘要: 为了满足地震精细解释的要求, 克服人工层位追踪中存在的层位误差, 提出了一种新的层位自动追踪方法。该方法以高阶统计量时间延迟估计为基础, 通过对人工追踪的层位进行高阶相关计算, 并实现层位的自动调整, 得到更加准确的层位文件。该方法采用四阶累积量函数进行计算, 不仅具有很强的抑制噪声的能力, 并可以通过高阶统计量的对称性质, 实现其快速算法。实际资料的层位精细处理结果表明, 该方法可以得到准确的层位文件, 具有很强的理论和实际应用价值。

Abstract: This paper presents a new method for tracing of horizons as required by detailed seismic interpretation, in order to eliminate the error in manual tracing of horizons. This method features strong noise elimination capacity, fast algorithm by four-order accumulative function and automatic adjustment of horizons in higher-order correlative calculation of manual-tracing horizons for getting more accurate horizons files. Case study shows that this method has strong theoretical and applicable values.

Key words: seismic interpretation, horizon tracing, noise, processing
