Fracture weaknesses are two important parameters to describe the characteristics of reservoir fracture-induced anisotropy. Accurate estimation for fracture is great significance seismic exploration and characterization naturally fractured reservoir, especially gas-bearing reservoir. Linear inversion based on Bayesian theory can fuse prior information. And inverse problem solved in form posterior probability density function (PDF) obtain maximum solution. Based PP-wave reflection coefficient...
Fracture weakness is one of the most important anisotropic parameters used to characterize fractures and identify fluids. The model horizontal transversely isotropic (HTI) medium usually utilized in seismic azimuthal inversion for fracture weaknesses. Low-frequency component weaknesses plays a significant role characterization fluid identification due deficiency low-frequency acquired data. commonly approaches estimate include smoothing constraints damped wave field complex-frequency domain....
For the problem of large number target detection algorithm parameters, a lightweight real-time YOLOv5s-MC based on improved YOLOv5s road scenes is proposed. firstly, CA attention added to model improve sensitivity network detect targets; secondly, in feature fusion network, add adaptive weight parameters using AS-Concat structure are better fuse information different layers and accuracy ; adding small layer tiny finally introducing Mobilnetv2, as overall backbone realize requirement network;...
The improvement of resolution and efficiency seismic inversion is one the key problems in reservoir characterization. We first express PP-wave (incident P wave, reflected or scattered wave) reflection coefficient transversely isotropic media with a horizontal symmetry axis (HTI) form Fourier coefficients. Then, we analyze sensitivity coefficients to elastic parameters fracture weaknesses. results demonstrate that zeroth-order sensitive but insensitive normal shear weakness, second-order more...
Abstract The stratum can be modelled as a horizontal transversely isotropic medium when single set of vertically parallel fractures embedded in an background medium, which facilitates efficient study for fractured reservoirs. Elastic parameters and fracture weaknesses are important to describe the characteristics reservoirs, seismic inversion plays significant role estimation. commonly used deterministic methods do not fully utilize prior information fails present uncertainty analysis...
