Abstract：In view of higher resolution of Proni transform in time domain or frequency domain and providing attenuation parameters related to oil/gas at the same time,combining with synthetic seismogram of theoretical models,the paper discussed the noise-suppressed feature and stability of Proni filtering on the basis of the results studied by our predecessors and applied the Proni filtering to oil/gas prediction of field seismic data. There are three filtering parameters that are very important,that is pulse length Δτ,band width Δω and attenuation factor Δα,the optimum values of which are determined by experiments. The results of practical application showed that the Proni filtering is sensitive to attenuation by absorption of seismic wave in high frequency,by which the prediction of oil-bearing probability of bed can be effectively implemented,the successful rate of prediction is about 70%.
