Abstract:

The Seismic attribute analysis technology is always main research content of seismic special handling and the explanation.Along with oil gas exploration development,The seismic attribute analysis technology already became the core content of the oil deposit geophysics research,It is link between exploration seismology and development seismology.This article in view of Ordos basin low scope structure,low porosity,low permeability,hiding oil gas pool characteristic,After the synthesis application coherent data body analysis,phase automatic sorting qualitative recognition granulated substance body thickness,the seismic amplitude attribute analysis,the frequency spectrum decompose,the multi- wells restraint reservoir folds the inversion and so on to fold the attribute analysis technology,Explored a set to suit this area oil gas characteristic the reservoir crosswise forecast and the oil gas recognition pattern.For this area oil gas exploration development,The calculation of reserves provides the reliable basis.At the same time the experience for the oil gas pool exploration development is also accumulated.
