Abstract :
To monitor fluid flow dynamically and obtain more reliable gas reservoir information of 3D time-lapse seismic data, in this paper we present a 4D-AVO inversion algorithm, in which visualization technology, cross-correlation technology, time and phase shift theory, matched filtering algorithm and normalization technology are used to correct and analyze time-varying seismic data after AVO inversion. Some experimental 3D time-lapse seismic data of CDP trace gathers are analyzed. The results show that it is an efficient way to estimate the volume changes made by the exploiting of oil and gas reservoir while clearly show the changes in oil reservoir area.
