摘要
通过Wigner-Ville分布和平滑Wigner-Ville分布的模拟信号对比,表明平滑Wigner-Ville分布可以自适应的调节窗口长度,成为一种有效地消除交叉项的方法。为有效提取低频信息进行储层预测,我们利用基于平滑Wigner-Ville的谱分解技术预测油气,针对含油气储层引起地震波高频能量衰减和低频能量增强的特点,将平滑Wigner-Ville分布应用到某工区进行叠后资料处理,通过谱分解不同频率的切片响应,得到目的层段上的低频异常现象,表明基于高分辨率平滑Wigner-Ville分布的地震谱分解技术能够更好地表征目的层的油气分布情况。
Making a comprasion of the analog signal contrast of Wigner-Ville distribution with those of smooth Wigner-Ville distribution,it is shown that the smooth Wigner-Ville distribution can adjust the window length,which beacomes an effective method to eliminate the cross terms.For reservoir prediction based on the effective extraction with the low-frequency information,we use the smooth Wigner-Ville spectral decomposition technique for prediction of oil and gas reservior,and by making seismic waves of high energy attenuation and low-frequency energy enhancement features.Then we apply the smooth Wigner-Ville distribution in the working area for post-stake data processing,through the different frequency slice response of spectrum decomposition,and get the abnormal phenomenon of low frequency in target layer.The results show that based on high resolution smooth Wigner-Ville distribution,can point out thin layer better.
