摘　　要：在四维地震监测中,重复观测的三维地震数据存在许多不合理差异。为了获得更加可靠的油藏信息,实现油藏的动态监测,应用四维地震反演多参数校正算法,对四维地震数据进行校正。该算法运用归一化技术计算校正算子,对地震数据进行差异校正与分析。通过对工区中一块地震数据进行试验,结果表明,该方法能够有效地消除地震数据中不合理的差异,并显示油藏发生变化的区域,估算油藏中由于油气开采产生的体积变化。During the 4D seismic monitoring,there were many differences in the repeated observations of 3D seismic data.In order to obtain more reliable gas reservoir information and monitor gas reservoirs dynamically,a correction algorithm based on 4D seismic inversion was applied to correct the seismic data,in which a normalized technology was used to calculate the correctors to correct and analyze the seismic data.Through an experiment of the seismic data in the operation area,the result shows that this algorithm is an effective way to eliminate the unreasonable differences in seismic data,indicate the changes in reservoirs and estimate the volume changes of exploiting of oil and gas reservoirs.
