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。
In the 4-D seismic monitoring, there are many unreasonable differences in 3D seismic data that are repeatedly observed. In order to obtain more reliable reservoir information and realize the dynamic monitoring of reservoir, the 4-D seismic inversion multi-parameter correction algorithm is applied to correct the 4-D seismic data. The algorithm uses the normalization technique to calculate the correction operator and corrects and analyzes the seismic data differently. The test results show that this method can effectively eliminate the unreasonable differences in seismic data and show the areas where the reservoir is changing, and estimate the volume change in the reservoir due to the oil and gas exploration.
