Full-waveform inversion (FWI) utilizes optimization methods to recover an optimal Earth
model to best fit the observed seismic record in a sense of a predefined norm. Since FWI …

摘要以煤层瓦斯富集地质理论为基础, 根据煤层瓦斯与常规砂岩储层天然气赋存机理的对比,
提出了以煤层割理裂隙为探测目标的煤层瓦斯富集AVO 技术预测理论. 根据AVO 理论模拟 …

E xploration and drilling for natural gas in North America has moved radically away from
conventional reservoirs to focus on unconventional reservoirs such as tight gas sands and …

Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by
solving an inverse problem based on seismic measurements. There are at least three …

常规的地震道反演方法建立在反射P 波垂直入射假设的基础上, 而实际地震资料采集时多数是非
零炮检距的, 反射振幅是共中心点道集叠加的结果. 因此, 利用常规地震道反演方法就不能得到 …

Frequency-dependent amplitude versus offset (FAVO) inversion is a popular method to
estimate the frequency-dependent elastic parameters by using amplitude and frequency …

To overcome the weaknesses of conventional prestack amplitude variation with angle
inversion based on various linear or quasi-linear approximations, we have conducted a …

Abstract In the Niger Delta, the Jay Field offshore structural model and seismic attribute
analysis were carried out to enhance prospect evaluation and mitigate risk in field …

In situ stress has a significant effect on the properties of underground formations, including
seismic wave velocity, porosity and permeability, and further affects seismic reflectivity and …

The plane-wave reflection coefficient (PRC) plays a remarkable role in conventional
amplitude variation with offset (AVO) analysis and inversion. Compared with the widely …
