The Zoeppritz equations describe the relationship between seismic properties that are
useful for the interpretation of lithology and fluid properties. Various approximations to the …

摘要杨氏模量与密度乘积(犈ρ) 能够突显页岩气储层的异常特征, 泊松比能够指示储层的含流体
性. 与常规叠前弹性参数反演相比, 基于犈ρ, 泊松比和密度的叠前纵横波联合反演可以获得更加 …

With the increase in exploration target complexity, more parameters are required to describe
subsurface properties, particularly for finely stratified reservoirs with vertical transverse …

Unconventional hydrocarbon reservoirs, such as shale rocks, are generally transversely
isotropic with a vertical axis of symmetry (VTI). The identification of sweet spots in these …

摘要常规三维地面地震反演不可避免的存在多解性和分辨率不高的缺陷, 而油藏地球物理阶段
丰富的多尺度地震资料为减小多解性, 提高分辨率提供了可能. 基于贝叶斯反演理论 …

Inversion of seismic reflection coefficients is formulated in a Bayesian framework. Measured
reflection coefficients and model parameters are assigned statistical distributions based on …

With the increasing mining depth of coal mines, geologic hazards have become the main
source of accidents. For this reason, coal seam prediction requires more assessment …

The product of Young's modulus and density can highlight abnormal characteristic of shale
gas reservoirs. Poisson ratio can indicate fluid property. Compared with conventional pre …

摘要AVO 反演可以获得地层岩性和流体信息, 而叠前反演问题都是高维的和非适定的,
因此获得可靠稳定的解对叠前反演至关重要. 本文给出了一种基于贝叶斯理论的纵波和转换波 …

Multiwave seismic technology promotes the application of joint PP-PS amplitude versus
offset (AVO) inversion; however conventional joint PP-PS AVO inversioan is linear based on …
