Petrophysical amplitude variation with offset (AVO) inversion, which combines a rock-
physics model and prestack inversion, aims at effectively quantifying reservoir-property …

Changes in reservoir parameters cause differences in seismic response characteristics,
which can reflect the formation lithology and fluids. We conduct seismic physical modeling …

Natural fractures play a significant role in oil and gas reservoirs. Accurate predictions of
fracture parameters are vital in reservoir prediction and oil and gas development. The …

This paper first gives a brief review of the historical development of shear-wave splitting and
P-wave azimuthal anisotropy in oil and gas seismic exploration, and focuses mainly on their …

四十年前, 地壳中的横波**现象首次在天然地震中得到证实, 并引入到勘探地震领域.
回顾了横波**研究的发展历史, 重点阐述横波**的由来, 原理及其在裂缝性油气藏描述中的 …

Fractures usually spread over various scales and strongly influence velocity and anisotropy.
We investigate elastic velocity and anisotropy in rocks with fractures of different sizes. Based …

The fractional Brownian field is often used to reproduce the fractal properties of complex
heterogeneous media, which closely represent real-world geological materials. Studying …

本文首先回顾了横波**和纵波方位各向异性应用于油气勘探的发展历程;
在此基础上重点讨论了二者在上地壳中的分布情况, 相互关系及应用条件 …

Oil and gas reservoirs usually contain horizontal fractures that develop along bedding and
have a non-negligible effect on reservoir characteristics. When the horizontal fracture is …

Seismic amplitude variation with offset (angle) data contains information on the elastic
parameters. The most commonly studied elastic parameter group is P-wave velocity VP, S …
