The paper introduces the core theories, architecture and functions of pre-stack AVA inversion and reservoir prediction software system. This system is based on modem software engineering theory and was designed by structured data management and componentization software framework. It is a pre-stack inversion and reservoir prediction system used for lithology prediction, physical parameters and hydrocarbon potential prediction. By using simulated annealing pre-staek simultaneous AVA inversion, seismic attributes optimization and integration, Kohonen self-organizing reservoir cluster analysis and MLP muhilayer preceptor non-linear reservoir parameters prediction, reservoir spatial distribution characteristics can be delineated more accurately and reservoir parameters can be estimated quantitatively, therefore, the heterogeneous reservoir prediction problem was solved. This system has been applied to many work areas and achieved high consistency between prediction and actual drilling results. The interface development database and basic algorithm database also provide a basic platform for the integration of new techniques and new methods.
