Application of pre-stack constrained stratigraphic inversion technique in reservoir prediction of glutenite

Traditional post-stack impedance inversion performs inversion of post-stack seismic data.It is a better technique to describe subsurface lithologic character.But it could not get an exact reservoir prediction to heterogeneous reservoir.Pre-Stack Constrained Stratigraphic Inversion Technique is based on a bayesian formalism.It performs simultaneous inversion of multiple angle stacks.This inversion combines pre-stack seismic amplitude and could predict heterogeneous reservoir much better.Pre-Stack Constrained Stratigraphic Inversion is applied to glutenite reservoir prediction at steep slop structure zone in north Dongying Sag and sculpts glutenite reservoir Spatial Distribution.
