摘要: 在四维地震油藏监测技术应用中,四维地震数据由于不同时间的采集与处理以及噪音等因素的影响,在地震剖面上存在很多不合理差异。为了获得真正由于油藏内部油气水变化引起的地震响应差异,必须对四维地震数据体进行归一化校正。针对四维地震数据在时间、振幅、频率和相位方面的差异,论述了四维地震数据归一化处理的原理,提出了寻找最佳匹配滤波器获得校正归一化算子的处理方法;对国外某一地区的一块四维地震资料进行了实际处理,结果是令人满意的,表明了方法的有效性。

Abstract: In four-dimensional (4-D) seismic reservoir monitoring,due to different vintages of data requisition and processing philosophies,as well as noisy factor,4-D seismic data have significant unreasonable differences between two profiles.In order to obtainthe real seismic differences resulting from the changes of oil,gas and water in reservoir,4-D seismic datasets should be well normalized.In this paper,we discussed the principle of normalization processing for 4-D seismic data focusing on the differences inseismic time,amplitude,frequency and phase.A processing method based on finding a best match filter is presented.Then thenormalization processing for timelapse seismic has been applied to the field 4-D data.The normalized results are satisfactory,which shows that the method is effective.
Key words: 4-D seismic, data processing, normalization, difference analysis, operator
