Abstract：On the basis of detection,combination and optimization of seismic attributions and under the constraint of logging porosity data,the paper studied using seismic attributions for inversion of porosity parameters,in which quadric program inversion is adopted,that is,on the basis of detecting seismic attribution,the objective function of seismic attribution and porosity of some borehole is built up, the inversion calculation is carried out by taking the relation between seismic attribution and porosity of other borehole as a constrained condition.We calculated inversion for two boreholes and proved the results by extrapolating to second bolehole on the basis of inversive result of first borehole,the extrapolated inversive result of second borehole is compared with the calculated results for same borehole,and then inverse process as above mentioned from second to first borehole is carried out.The comparison with logging data and the analysis of real data inversion results showed that the method is feasible and the results are correct.
