The propagation of seismic waves in attenuating and anisotropic earth media is
accompanied by amplitude attenuation and phase distortion. If these adverse effects are not …

Strong subsurface attenuation leads to distortion of amplitudes and phases of seismic waves
propagating inside the earth. Conventional acoustic reverse time migration (RTM) and least …

摘要介质的黏滞性是普遍存在的. 黏滞性介质中的真振幅成像需要校正由介质的黏滞性引起的
振幅衰减与速度频散, 然而常规的反犙偏移方法存在不稳定问题. 本文在反演的框架下求解黏声 …

Attenuation of seismic waves needs to be taken into account to improve the accuracy of
seismic imaging. In viscoacoustic media, reverse time migration (RTM) can be performed …

Due to the energy attenuation and phase distortion of seismic waves propagating in viscous
media, it is difficult to obtain high resolution and amplitude preserved migration images …

Anisotropic and attenuating properties of subsurface media cause amplitude loss and
waveform distortion in seismic wave propagation, resulting in negative influence on seismic …

地下介质中普遍存在各向异性及黏滞性, 各向异性会使地震波走时发生变化,
黏滞性会使地震波发生振幅衰减和相位畸变. 在进行地震资料偏移成像时 …

We have developed a new time-domain viscoacoustic wave equation for simulating wave
propagation in anelastic media. The new wave equation is derived by inserting the complex …

The calculation of the gradient in full-waveform inversion (FWI) usually involves
crosscorrelating the forward-propagated source wavefield and the back-propagated data …

Seismic waves are attenuated during propagation. The unwanted attenuation effects in
migrated images make interpretation difficult. Based on the dissipation mechanism in a …
