Abstract

Some new computational techniques are suggested for estimating symmetry axis azimuth of fractures in the viscoelastic anisotropic target layer in the framework of QVOA analysis (Quality factor Versus Offset and Azimuth). The different QVOA techniques are compared using synthetic viscoelastic surface reflected data with and without noise. I calculated errors for these techniques which depend on different sets of azimuths and intervals of offsets. Superiority of the high-order “enhanced general” and “cubic” techniques is shown. The high-quality QVOA techniques are compared with one of the high-quality AVOA techniques (Amplitude Versus Offset and Azimuth) in the synthetic data with noise and attenuation. Results are comparable.
QVOA裂缝方向估计技术
在QVOA分析的框架下,提出了一些新的计算技术来估计粘弹性各向异性目标层中裂缝的对称轴方位。使用有噪声和无噪声的合成粘弹性表面反射数据来比较不同的QVOA技术。我计算了这些技术的误差,这些误差取决于不同的方位角和偏移间隔。显示了高阶“增强的一般”和“三次”技术的优越性。在有噪声和衰减的合成数据中,将高质量QVOA技术与高质量AVOA技术之一(振幅与偏移和方位)进行了比较。结果具有可比性。
