摘要
非重复采集地震资料进行时延地震一致性处理时,首先需要消除两期资料观测系统的差异.在分析同一区块不同时期地震资料观测系统差异的基础上,本文提出共反射点道集抽取方法,大幅度提高了两期资料观测系统的一致性,为后续的时延地震一致性处理打下基础.
In non-repeatable time-lapse data processing, the primary step is to eliminate the influence caused by the difference of the two observation systems. On the basis of the analysis of differences in the same block in different periods of seismic observation systems, we put forward common reflection point gathers extraction method, which has greatly improved the consistency of two data observation systems. Our method provide better consistency for the subsequent time-lapse seismic processing.
