摘要:

频率是地震波的一个重要属性,地震频率一致性处理是时延地震处理过程中关键的一步.本文提出的时延地震互约束频率一致性处理方法,能够消除两期资料非油藏部分带有的不应该有的频率差异,保证不同时期地震资料频率的差异仅来自油气储层的流体变化,为后续的处理研究奠定了基础.

Abstract:

frequency is an important attribute of seismic wave, and the frequency consistency processing is a key step in the process of time-lapse seismic data processing. The time-lapse seismic mutual constraint frequency consistency processing method in this paper, can eliminate the frequency difference, which should not exist, from non-reservoir factors of the two periods data, ensure the differences are only derived from the fluid changes of the reservoir, and laid the foundation for the subsequent processing and research.
