Shales represent strongly intrinsic vertical transverse isotropy (VTI) property or polar
anisotropy. The presence of vertically aligned fractures makes shale exhibit orthogonal …

Homogeneous isotropic or vertically transverse isotropic rocks containing a single set of
aligned, vertical fractures exhibits an effective long-wavelength horizontally transverse …

As has been known for some time, velocities of elastic waves propagating in most
subsurface formations exhibit directional dependence, or seismic anisotropy. On their way to …

摘要裂缝型储层表现出较强的各向异性特征. 缝隙中充填不同流体时, 裂缝储层的地震响应特征
也不相同. 本文从各向异性岩石物理模型出发, 引入可有效识别缝隙流体的指示因子 …

长波长假设条件下, 各向同性背景地层中发育一组平行排列的垂直裂缝可等效为具有水平对称轴
的横向各向同性(HTI) 介质. 基于不同观测方位的岩石地震响应特征变化, 宽方位地震数据不仅可 …

高角度缝隙充填的碳酸盐岩储层可以等效为具有水平对称轴的横向各向同性介质.
本文提出了适用于裂缝型碳酸盐岩的岩石物理模型构建流程, 重点介绍了在碳酸盐岩各向同性 …

We develop a data-driven model discovery and system identification technique for spatially-
dependent boundary value problems (BVPs). Specifically, we leverage the sparse …

实际勘探表明页岩储层中往往背景呈现出很细的水平层理, 垂直裂缝出现在多组页岩细层中,
这种裂缝储层结构不能用传统的HTI 模型来准确描述, 但是可以用正交各向异性介质很好的描述 …

Horizontally and vertically aligned fractures (joints) permeated in an isotropic background
can give rise to a long-wavelength equivalent orthorhombic medium, which is common for …

Horizontal layered formations with a suite of vertical or near-vertical fractures are usually
assumed to be an approximate orthotropic medium and are more suitable for estimating f …
