| 摘 要： | 本文将黏弹固体骨架与各向异性多孔弹性模型相结合,并将地层黏弹性的特性考虑其中,更好地刻画了快P波和横波在地震频带的衰减现象。将多孔黏弹模型模拟结果同传统弹性模型模拟结果对比显示,多孔黏弹模型在模拟真实储层方面更具优势。

| Abstract: | This article combines viscoelastic solid skeleton with anisotropic porous elastic model and takes the impacts of viscoelastic properties of layer into consideration，providing a better explanation of fast P- wave and S- wave attenuation phenomenon in the seismic band． The stimulation results indicate that in comparison with porous elastic model，viscoelastic- porous model optimizes the stimulation of real reservoir． |
