| 摘 要： | 从讨论实际地震记录高阶累积量分析入手,研究利用高阶累积量计算高阶谱的方法.在分析高阶累积量及高阶谱提取分离具有非高斯分布信号时,详细讨论了产生非高斯分布的地震记录的特征规律.阐明了用地震资料的低频高阶谱预测砂体含油气性的机理.从理论模型和实际资料论证了研究方法的正确性.最后利用该方法计算的高阶谱结果和实际产油气井资料进行符合率验证分析.在此基础上,利用该方法进行有利含油气层预测.

| Abstract: | On the bases of researching structure and deposit in oil-gas field,we study the new method of prediction oil and gas by seismic data.We research the approach of calculating high order spectrum utilizing high order accumulation through analyses actual seismic data.When the non-Gauss distribute information is collected by means of analyzing the high order spectrum utilizing high order accumulation,the geological condition and reason of coming into Gauss and non-Gauss distributes is discussed.We clarify the mechanism of prediction oil and gas using seismic lower frequency data.The method is approved through theory model ,finally the bearing gas well according high order spectrum results of being calculating with researched the method is analyzed.On the base,we conduct to predict the better gas layers. |
