Abstract:

The processing method of combining well log constrained seismic trace inversion with polynomial fitting technique was used to improve the resolution factor of seismic records.The purpose was to make full use of the ready information of well log,geological and seismic data to constrain seismic trace inversion so as to obtain an opproximate reflectivity sequence section with higher resolution factor and wider band,and then use lateral polynomial fitting technique to process the section.This method does not only improve the resolution factor of seismic records,but also the signal/noise ratio of the records.This method was used to process some seismic data of a certain area,the result was evident.

Key words: well log constrain, seismic trace inversion, resolution factor, signal/noise ratio, polynomial fitting
