There is a problem in forecasting thin sandstone in development with the earthquake in the area with dense well network.The research was done on Saertu oil bed in the first northeast area of Lamadian reservoir.Make use of the fuzzy system as recovery of the low frequency of the wave impedance inversion,and use the para-wave impedance remodeling inversion as the compensation of the high frequency,the broadband remodeling inversion came true.The remodeling inversion result not only the thick sandstone more than 5 meters and the thin sandstone less than 2 meters could be recognized.As a result,sedimentary phase modified by well to seismic integration after the vertical contact and spatial distribution of sandstone accurately locating,provided the reliable analysis inference for the research of the remaining oil in the thin sandstone.
