摘要
在时移地震实际生产中总是存在不一致性的因素,主要表现在时间信号延迟、信号能量差异、信号的带宽差异及相位差异等4个方面。为了消除或减少这些不一致性因素,在时移地震资料处理中,出现了4种互均衡技术:资料的时间移动,均方根能量补偿(也叫振幅均衡),带宽均衡及相位均衡。通过模拟出不同时间存在的振幅、时间、相位、频率等单因素差异,再用互均衡技术对地震记录分别进行振幅、时间、相位、频率等单因素校正,获得了较好的结果。
The inconsistent factors always existed in practical time-lapse seismic work,and four aspects mainly came out: time-delay of signal,energy difference of signal,bandwidth difference of signal and phase difference.In order to remove or reduce the inconsistent factors,there are four cross equilibration techniques in time-lapse seismic data processing: time shift of data,mean square root(msr) energy compensation(amplitude equalization),bandwidth equalization and phase equalization.The paper simulated amplitude,time,phase,frequency as single ingredient difference from different times,and corrected seismic data in amplitude,time,phase,frequency by cross-equalization technique,obtained better outcome.
