Abstract：The reef bank carbonate reservoirs are characterized by various pore types and complex relationship between porosity and permeability. Due to the lack of corresponding rock physics models,seismic prediction of reservoir permeability has been a difficult problem for a long time. Taking Puguang Gasfield as an example,the controlling effect of complex pore types on reservoir permeability and logging response characteristics of different pore types are analyzed,and frame flexibility factor is introduced in this paper to characterize the rock physical parameters variation of samples with similar porosity. In order to make fine interpretation and evaluation of reservoir logging permeability,the discrimination standard of reservoir pore types and reservoir porosity-permeability model are established based on the frame flexibility factor. Rock physical model based on the frame flexibility factor is finally established by analyzing the relationship between elastic parameters of reservoirs with various pore types and the frame flexibility factor. Quantitative prediction of reservoir permeability with complex pore types is realized by pre-stack geostatistical inversion of permeability based on porosity and the frame flexibility factor.
