| 摘 要： | 主要是从信号的高阶统计量这个新角度，采用高阶谱时频分析方法，研究信号的Wigner双谱性质，达到识别和提取地层含气而产生的地球物理异常。结果表明高阶统计量技术能较有效地提取出地震信号的异常反射，且显示直观，便于解释，为提高碳氢检测的可靠性提供新的信息。

| Abstract: | From the high-order statistics of signals and the time-frequency analysis of high-order spectrum, the Wigner bispectrum attribute is studied to recognize geophysical anomalies due to oil existence in the strata. The interpreted results show that high-order statistics technique can effectively extract anomaly information of seismic signals. It can give a clear visual display to help us quickly interpret, and thus can provide new information for enhancing the hydrocarbon prediction reliability. |
