[Abstract]:In order to solve the problem that the heterogeneity of bioclastic beach reservoir is strong, and it is difficult for conventional geophysical techniques and methods to accurately predict its reservoir and physical properties, a set of seismic microphase analysis and phase-controlled reservoir inversion are studied and formed. The method flow and key technology of lithoclastic beach reservoir and physical properties prediction are integrated with phase-controlled porosity prediction. The results show that the seismic microphase analysis of "flat profile fusion" can be realized by the interpretation of plane sedimentary facies based on waveform clustering and the phase analysis technology of profile seismic phase monitoring. The organic combination of phased lithologic average velocity filling modeling and colored inversion can realize the prediction of cuttings beach reservoir in low exploration area (less well or no well area). The conversion of velocity to porosity under the control of sedimentary structure and sedimentary microfacies can effectively solve the problem of predicting the physical properties of bioclastic beach reservoir in low exploration area. The example shows that the method flow and key technology are effective for predicting the physical properties of bioclastic beach reservoir.
